Every parent waits eagerly for the day their child takes those wobbly first steps. For many, it's more than just a motor milestone—it’s symbolic of growth, independence, and progress. While the typical age range for walking spans from 8 to 24 months, the reason why some children walk earlier than others has remained an enigma—until now.

New research from a team of scientists across the University of Surrey and the University of Essex, published in Nature Human Behaviour, reveals that genetics may be a key player in determining when babies begin to walk. The study, one of the largest of its kind, analyzed genetic data from over 70,000 infants and found that nearly a quarter of the variation in the age at which children begin to walk can be explained by their DNA.

The onset of walking, termed Age of Onset of Walking (AOW) is widely recognized as a clinical marker for brain and behavioral development. Researchers conducted a genome-wide association study (GWAS) that examined the DNA of infants from four major European-ancestry cohorts, including the United Kingdom Medical Research Council, the Netherlands Twin Register, and the Norwegian MoBa cohort.

What they uncovered was striking- 2,525 significant genetic variants were associated with AOW, of which 11 loci remained statistically robust. Among these, certain genes were found to be strongly expressed in the brain, particularly in areas responsible for motor control like the cortex, cerebellum, and basal ganglia.

Further analysis revealed that walking later but still within the typical developmental window—was genetically linked to higher cognitive performance and reduced risk for ADHD. This suggests that a child who walks later might actually be developing brain functions that support focus and learning.

Why Walking is More a Brain Activity than Muscle?

The act of walking involves a complex interplay between muscles, balance, sensory feedback, and brain coordination. The study showed that many of the genes related to delayed walking were also enriched in processes involving neuron generation and neurogenesis—the very building blocks of brain function.

Interestingly, the researchers also identified overlaps between walking onset genes and those associated with autism, intellectual disability, and educational attainment. This does not mean that walking later is a cause for concern; rather, it highlights how intertwined motor milestones are with broader neurological development.

Moreover, the polygenic scores—an estimate of genetic predisposition—were found to correlate with brain volume and cortical folding patterns in neonatal MRI scans. This reinforces the notion that motor development may reflect deeper, genetically driven processes within the brain.

Is Late Walking a Warning Sign?

While delayed walking can sometimes point to developmental disorders, most late walkers fall within the wide spectrum of normal development. According to Professor Angelica Ronald, a senior researcher on the study, “Only a minority of late walkers have underlying neurological abnormalities. In most cases, the timing is just one part of the child’s individual developmental rhythm.”

Still, the 18-month mark remains an important pediatric checkpoint. Children who haven’t begun walking independently by then may benefit from a medical evaluation to rule out conditions like cerebral palsy, muscular dystrophy, or developmental coordination disorder.

Although genetics play a significant role, they are only one part of the story. Environmental influences—such as nutrition, gestational age, opportunity to practice movement, and cultural norms—also shape when a child learns to walk. For instance, children in cultures that emphasize early motor training often walk sooner, regardless of genetic predispositions.

Moreover, the researchers noted that their findings, while robust, were limited to populations of European ancestry. Future studies including diverse populations will help uncover whether these genetic markers are universally applicable or ethnicity-specific.

This study provides more than just a scientific breakthrough—it offers reassurance. Your baby’s timeline isn’t a race, and walking “late” might simply reflect a different kind of neurological development in progress.

Recognizing Baby Walking Styles

Babies have their own unique walking styles, and many are completely normal as their muscles and bones develop:

The Toddle: A wide-legged, deliberate style that becomes smoother over time.

The Cowboy: Bow-legged with knees apart and ankles together—a temporary phase.

The Duck: “Out-toeing” or “in-toeing” where toes point outward or inward; usually resolves with growth.

Toe Walking: Walking on tiptoes, common in early stages of walking.

Tips to Encourage Your Baby to Walk

Alongside a baby’s first smile and first word, those very first steps are a big deal. For many parents, it's an eagerly awaited milestone—camera in hand, ready to capture the magic. But behind those few wobbly steps lies months of motor development: sitting, rolling, crawling, and standing. And as this moment approaches, it’s natural to wonder—are they walking differently than other kids? Is there a way to help them along?

Here are six practical and parent-approved tips to gently support and encourage your baby’s walking journey:

1. Let Them Go Barefoot

While baby shoes are adorable, barefoot is best during those initial walking phases. Walking is a complex task, requiring your baby’s bones, tendons, and muscles to adjust and work in sync. Bare feet help your child better sense their footing and improve balance—crucial in building confidence and coordination.

2. Use Toys as Motivation

Encouragement can come in the form of fun! Hold out a toy—or even the irresistible TV remote—just out of reach to motivate your baby to take a few steps. Position yourself strategically and cheer them on as they inch closer.

3. Create a Furniture Path

Turn your living room into a mini obstacle course by placing pieces of furniture close together. This gives your little one a safe way to “cruise” from one surface to another. As they gain confidence, increase the gap between objects to gradually build strength and independence.

4. Check the Flooring

Slippery surfaces can make walking harder. Avoid glossy tiles or slick laminates early on. Opt instead for carpeted areas or lay down rugs and yoga mats for better grip and safety while they’re learning.

5. Pick the Right Push Walker

Choose a push-along walker like a trolley with blocks inside, instead of a sit-in, wheeled version. The American Academy of Pediatrics (AAP) has recommended banning sit-in baby walkers due to safety concerns. Push-along types support forward movement while helping babies develop stability and control.

6. Steady and Encourage Them Emotionally

Support matters. Position your baby against a stable surface and sit opposite them. Gently encourage them to move forward. Keep the mood upbeat with claps, songs, and smiles. Remember, babies mirror emotions—your confidence and joy fuel theirs. A tumble or two is normal—what matters is consistent encouragement.

When to Talk to Your Pediatrician?

Not all differences are concerning, but you should consult a doctor if you notice:

Asymmetry: One foot dragging, or one side moving differently than the other.

Frequent Falls: Some tripping is normal, but consistent stumbles could signal an issue.

Signs of Pain: Limping or discomfort while walking shouldn’t be ignored.

So the next time you're asked, “Is your baby walking yet?”, you can confidently say, “Not yet—and that's perfectly fine. It’s in their DNA.”

Walking is not just a physical milestone—it’s a reflection of both genetics and neurodevelopment. With nearly 25% of walking-age variability explained by genetic factors, science is now rewriting the way we understand infant development, one step at a time.

A baby is considered fully developed and full-term at 39 weeks of gestation. A baby can be born anywhere between 37 and 42 weeks and can still be considered full-term. This period helps in baby's organ development like brain, lungs, and liver. It also reduces baby's health risks, promotes a better brain development and helps with other cognitive activities.

However, under certain circumstances, premature babies are also born. However, when a baby is born at 24 weeks or later, the baby has chance to survival and this chance increases with each additional week of gestation. However, babies who are born before 24 weeks face a high risk of mortality and potential long-term health issues.

A baby born before 22 weeks has a survival rate of 6%. So if a baby born in 21 weeks survives, it is no less than a miracle.

This is the story of one such miracle that happened where a baby, who had less than 1% chance of survival is now thriving and has broken the world record.

"Defied All Scientific Odds"

This is from the year 2020 when at 21 weeks, in Alabama, the most premature baby in the world, as per the Guinness World Records, was born.

Curtis Means and his twin sister, C'Asya Means, were born on July 5, 2020, at the University of Alabama at Birmingham (UAB) Hospital. Delivered at just 21 weeks and 1 day of gestation—132 days premature—the twins faced overwhelming odds, with UAB estimating their chance of survival at less than 1%. According to Guinness World Records, they were born nearly 19 weeks early.

"Numbers show that babies born so young have little to no chances of survival," said Dr. Brian Sims, a professor of pediatrics at the UAB who was the on-call physician when the twins' mother, Michelle Butler. The doctor's statement is part of UAB's official statement.

However, C'Asya did not respond to treatment and died the day after birth, but Curtis' heart rate and oxygen levels started to improve.

"We have never been able to bring a baby that young to the neonatal intensive care unit, so [Curtis] was literally the first of his kind," Sims told Guinness World Records. We were in uncharted territory."

Curtis received constant medical care that helped him breathe. His body temperature was also regulated and other care, including enough nutrition intakes were maintained. It was in about three months, when the doctors were finally able to take him off a ventilator.

Dr Colm Travers, an assistant professor in the Division of Neonatology said in a statement, "Curtis defied all scientific odds." Indeed he did. Age and birth weight are two of the most important factors in determining a newborn’s chances of survival, he explained. The odds are also higher if the baby is female, not part of a multiple birth, and if the mother received steroids before delivery to aid lung development—none of which applied in Curtis’s case. Yet, Curtis survived.

How The Baby Survived

At birth, Curtis weighed just 14.8 ounces (420 grams)—roughly one-seventh the weight of an average full-term newborn, according to Guinness World Records. Despite the odds, he grew stronger each day and was discharged from the hospital around nine months later, supported by medication, a feeding tube, and bottled oxygen.

After celebrating his first birthday, Curtis—affectionately nicknamed "Poodie" by his family—was officially recognized by Guinness World Records as the most premature surviving baby.

Six months after his discharge, Curtis’ medical team gathered outside the University of Alabama at Birmingham hospital to surprise his mother with the Guinness World Record certificate. The previous record holder, Richard Hutchinson, had been born just a month earlier, on June 5, 2020, at 21 weeks and 2 days.

In a significant update to maternal health care, Australia is introducing new national guidelines on how pregnant women are tested for gestational diabetes.

The changes, released by the Australasian Diabetes in Pregnancy Society and published in the Medical Journal of Australia, mark the first major update to gestational diabetes screening in over a decade. These revised guidelines are expected to impact more than 280,000 pregnant women annually, streamlining care, reducing overdiagnosis, and focusing medical resources where they are most needed.

What Is Gestational Diabetes and Why Is Testing Important?

Gestational diabetes mellitus (GDM) is a temporary form of diabetes that occurs during pregnancy. It’s defined by high blood glucose (sugar) levels that are first detected while a woman is pregnant. In Australia, GDM affects nearly one in five pregnancies and has short- and long-term health implications for both mother and baby.

Though GDM usually resolves after delivery, women who develop it are seven times more likely to later develop type 2 diabetes. Identifying and managing GDM is essential because untreated cases increase the risk of:

Macrosomia (a baby born significantly larger than average), which can lead to birth complications and higher rates of caesarean sections

Pre-eclampsia, a dangerous condition involving high blood pressure and potential organ damage

Premature birth and other serious outcomes

Moreover, the screening process offers a gateway for introducing long-term health interventions like dietary advice, physical activity plans, and future diabetes prevention programs.

Why Are the Guidelines Changing?

While GDM screening and treatment are beneficial for many women, a one-size-fits-all approach has downsides. The new guidelines aim to balance the benefits of early detection with the potential harms of overdiagnosis. Studies and patient feedback have highlighted several concerns with the current system:

Women report stress, shame, and stigma after diagnosis

Limited access to specialist care and nutrition support

Some women adopt overly restrictive diets without professional guidance

Others are forced to change their maternity care provider or place of delivery due to a high-risk classification

The aim is to reduce unnecessary interventions for women at low risk, while enhancing care for those who truly need it.

What Exactly Is Changing?

The revised recommendations result from a broad review of current research and expert input from medical professionals and consumers. Here are the key updates:

Universal Screening Remains – But With Adjustments

All pregnant women without a prior diabetes diagnosis will still undergo routine screening between 24 and 28 weeks using the Oral Glucose Tolerance Test (OGTT). This test involves:

• Fasting overnight
• A baseline blood test
• Drinking a sugary solution
• Two follow-up blood tests over two hours

However, fewer women will undergo multiple OGTTs during pregnancy. Early testing will be more targeted based on risk.

Early Testing for High-Risk Women

Women with risk factors will be screened earlier in pregnancy, ideally between 10 and 14 weeks. The approach includes:

An HbA1c test (a non-fasting blood test that gives an average of blood sugar levels over the past 2–3 months) in the first trimester for women with risk factors such as:

• High body mass index (BMI)
• Previous large baby
• History of gestational diabetes

If results show high HbA1c or there’s a history of GDM, women may undergo an OGTT early in pregnancy.

Stricter Diagnostic Thresholds

The cut-off values for diagnosing GDM using the OGTT have been adjusted upward. This means only women with more clearly elevated glucose levels will be diagnosed. The goal is to avoid labeling borderline cases as diabetic when the risks and outcomes are minimal.

What Do These Changes Mean for Women?

The updated guidelines aim to make gestational diabetes care more precise and patient-centered:

• Fewer unnecessary diagnoses for women with mild or borderline glucose levels
• Improved access to services for those at higher risk
• Reduced stress and confusion from unclear diagnosis or overtreatment
• Stronger support systems for managing diet and physical activity safely

Importantly, women are encouraged to maintain open communication with their health care providers, especially if they have risk factors or symptoms like fatigue, excessive thirst, or frequent urination during pregnancy.

"What's Going On Inside The Baby's Brain?"

If you area a regular social media user, you have definitely come across a meme that reads the exact line and then is followed by clips of babies making a fuss. But, what if we tell you that you could actually know what is going on. Not just that, but these developmental milestone is what shapes their future.

The first two years of a baby’s life are nothing short of magical — and not just because of the first smiles or tiny giggles. It’s also the time when the brain is growing at lightning speed, forming the building blocks for everything from movement to memory, emotions to education. According to researchers at Cedars-Sinai Medical Center, this early brain development doesn’t just shape how a baby acts now, but how they’ll learn, behave, and stay healthy for the rest of their lives.

Let’s unpack what’s happening inside those rapidly growing baby brains — and why every cuddle, word, and interaction matters.

Brain Growth: Fast, Focused, and Full of Potential

In those first two years, a baby’s brain doesn’t just grow — it wires itself. Dr. Wei Gao, a neuroscientist leading brain imaging research at Cedars-Sinai, explains that the brain first develops the areas responsible for movement and senses (like seeing and touching). But very soon after, it’s the emotional and social areas that take center stage.

This is why the first year is so important for bonding. “You want to provide sensitive support to the baby so the baby can develop a secure attachment,” Gao explains. That attachment — those quiet moments of eye contact, soothing, and play — builds the emotional foundation for confidence, learning, and even future relationships.

Gao’s team has even mapped how parts of a child’s brain connect during early childhood. In a massive ongoing study, they’re tracking over 7,000 children from birth through age 10 to understand how environment and genetics shape brain wiring.

Too Much Screen, Too Little Growth?

Dr. Jane Tavyev Asher, director of Pediatric Neurology at Cedars-Sinai Guerin Children’s, warns about one major disruptor in the early years: screens. While the glow of a phone or tablet may keep a baby distracted, it can actually confuse the brain.

“When you expose that developing brain to rapidly changing images, it learns to focus on that — not on the real world,” Asher explains. That means less attention to slower, natural patterns like human speech, eye contact, and physical play — all key to learning to read, write, and think clearly later in life.

Genes and Brains

It’s not just nurture — nature plays a big role too. Dr. David Rowitch, deputy director of research at Cedars-Sinai Guerin Children’s, points out that nearly 80% of babies with a genetic condition show some neurological signs early on — whether it’s seizures, muscle weakness, or a brain structure difference visible on scans.

Modern genetic testing can now read a baby’s entire DNA — all 3 billion base pairs — offering clues not only about physical health, but also mental development. Combining this information with brain scans could help doctors catch problems early, intervene sooner, and even improve a child’s future school readiness.

Why Early Intervention Matters

The ultimate goal? To make sure no child falls behind. As Rowitch says, understanding how brain connections, genes, and environment come together helps us support each child — especially those at higher risk — to reach their full potential.
