When your child gets sick, the instinct to reach for antibiotics can be almost automatic. After all, we've been told for decades that these powerful medicines are the key to conquering infection. But what if that "quick fix" is silently reshaping your child's health in ways you never suspected? From tummy aches to chronic allergies and even developmental issues, new science is sounding an alarm about what repeated antibiotic therapy may be doing to little bodies. Before you agree to that next prescription, let's dig deeper into what's really happening in your child's system — and how to safeguard their health for the long term.

Antibiotics have revolutionized modern medicine with fatal infections such as pneumonia, strep throat, and bacterial meningitis are now curable, and thousands of lives have been saved through proper use of the medications. But when children—particularly those younger than two years old—are concerned, new studies are cautioning parents and doctors to be careful.

A recent study in the Journal of Infectious Diseases reviewed the medical histories of more than one million infants in the United Kingdom. The results showed a troubling correlation: frequent and early use of antibiotics in childhood might have lasting effects on a child's health. From disrupting gut microbiomes to making a child more susceptible to chronic diseases like asthma and allergies, overuse of antibiotics might be subtly changing pediatric health outcomes globally.

One of the deepest effects that antibiotics have on a child's body is by disrupting the gut microbiome. These drugs, though meant to target bad bacteria, sometimes fail to discriminate—destroying good bacteria within the gut in addition to the bad. And that's where problems start.

The gut contains trillions of microbes that contribute to digestion, immunity, and even mental health. If this system is disrupted at an early age, it may pave the way for inflammatory and allergic reactions in the future. The Rutgers Health study found that children who received multiple rounds of antibiotics before they were two were much more likely to develop asthma, food allergies, and hay fever. Risk increased with every course of antibiotics given.

Could Antibiotics Influence Brain Development?

The same research suggested an even more shocking possibility: a possible connection between early antibiotic exposure and intellectual disabilities. While this correlation needs more study for verification, it highlights a developing concern among pediatricians and researchers that the knock-on effects of antibiotic use may extend far beyond the gut.

Interestingly, the research did not identify a uniform association between antibiotic exposure and other conditions like ADHD, autism spectrum disorder, or autoimmune diseases like celiac disease and juvenile idiopathic arthritis. This difference highlights the complexity of how antibiotics affect the developing body, and it is implied that some systems are more susceptible to their impact than others.

In addition to the single child, a very real concern is growing antibiotic resistance. Antibiotic overuse and misuse—e.g., treating viral infections such as colds or flu with them—lead directly to drug-resistant bacteria. According to the Centers for Disease Control and Prevention (CDC), more than 35,000 people in the U.S. alone die every year from antibiotic-resistant infections.

What is particularly distressing about this for children is that they will frequently be put on antibiotics for viral infections for which antibiotics will not help. For instance, most upper respiratory infections, the common cold, and certain ear infections are viral and do not respond to antibiotic treatment. Yet, according to studies, half of all antibiotics prescribed to children are for precisely these conditions.

In a bid to eliminate genetic or environmental confounders, scientists even matched up siblings—one who was given antibiotics at an early age and one who wasn't. The outcomes were the same: children who had been exposed to more antibiotics were at greater risk for allergic and respiratory disease, family background aside. That's another indication that antibiotics themselves—rather than genetic factors or family practices—are likely the prime mover.

How Can Parents Properly Use Antibiotic at Home?

First, know that antibiotics are strong allies but not magical fixes. Antibiotics only work against bacterial illnesses—not viruses. Colds, flu, and most coughs won't benefit from antibiotics and could actually hurt a child's overall health if these medicines are abused.

If your child receives a prescription of antibiotics:

• Always use the dosing prescribed by your doctor and take the medication in full even if your child is already on the mend.
• Never reuse old antibiotics or pass them between kids.
• Request your child's doctor to determine whether a viral or bacterial infection, and if it even needs antibiotics.
• Store antibiotics properly and eliminate unused drug in authorized take-back locations.

Doctors everywhere are promoting what's called "antibiotic stewardship"—the responsible use of antibiotics. Hospitals, clinics, and public health organizations are developing new standards to guarantee antibiotics are only used when absolutely necessary. But parents have a role to play, too. By asking the question of whether each antibiotic is really needed, following proper hygiene, and keeping up with vaccinations, families can stem the danger of resistance and safeguard their child's future health.

Antibiotics are a part of modern medicine, but not without danger—particularly in growing bodies. As important as they should never be avoided when medically indicated, parents and pediatricians need to balance their use, particularly in children younger than two years old. As scientists learn more about the ways these medications affect long-term health, one thing is certain, less is more for antibiotics early in life.

World map based on the United Nations population projection shows that 85 per cent of babies in 2026 will be born in Asia and Africa. The probabilistic population projection for 2026 is based on the World Population Prospects 2024.

2026 Baby Boom: 64.9 Billion Births In Asia

The map reveals that Asia is expected to see 64.9 billion births in 2026. This will account for roughly 49 per cent of all births worldwide. While fertility rates in countries like China, Japan and South Korea have declined, Asia's population still is keeping up and is at the center of global demographics.

2026 Baby Boom: 47.6 Billion Births In Africa

Second on the list is Africa, with expected numbers of 47.6 billion births in 2026. This represents 35.9 per cent of the global total. This is also true due to continent's high fertility rates and young population structure..

2026 Baby Boom: How Does the Rest Of The World Look Like?

• Latin America and Caribbean are expected to see 9.3 billion births or a total of 7 per cent of the total.
• Europe accounts for only 4.6 per cent of the birth rate as compared to the global population.
• North America shares a 3 per cent, which also reflects low fertility rates, despite a population growth driven by migration.
• Oceania contributes 0.5 per cent of births.
• Antarctica has no permanent population.

2026 Baby Boom: South Korea's Birth Rate Increased

South Korea’s birth rate increased for the second consecutive year in 2025, offering cautious hope for a country that has grappled with a demographic crisis for nearly a decade.

Preliminary figures from the Ministry of Data and Statistics show the total fertility rate, the average number of children a woman is expected to have in her lifetime, reached 0.80 in 2025, up from 0.75 in 2024. Births had already begun recovering in 2024 following the pandemic, aided by government support measures, after eight straight years of decline that pushed the rate to a record low of 0.72 in 2023 amid soaring housing costs and greater female workforce participation.

The crude birth rate rose to 5.0 births per 1,000 people in 2025 from 4.7 the year before. For comparison, China recorded 5.6 last year, Taiwan 4.6 and Japan 5.7 in 2024, where the overall trend is still downward.

The rebound has been quicker than the government’s optimistic forecast, which had projected 0.75 in 2025 and 0.80 in 2026, with fertility expected to cross 1.0 by 2031.

Marriage rates, often a leading indicator of future births with a lag of one to two years, climbed 8.1% in 2025 after jumping a record 14.8% in 2024. Officials attributed this partly to a larger population in their 30s and gradually shifting social attitudes.

The biggest rise in births occurred in the capital. Seoul’s fertility rate increased 8.9% to 0.63 from 0.58 in 2024, though it remains the lowest in the country.

Experts say the numbers still require careful interpretation because demographic composition changes can affect statistics. Even so, they view the improvement as a positive signal that may encourage more people to consider parenthood.

A 2024 government survey found 52.5% of South Koreans held positive views about marriage, up from 50.1% in 2022, and respondents ideally wanted 1.89 children on average.

Births increased 6.8% to 254,457 last year, the biggest rise since 2007. However, deaths also grew 1.3% to 363,389, meaning the population declined naturally for the sixth year in a row.

Infertility is no longer limited to couples in their 30s and 40s. Doctors are now seeing a steady rise in patients in their 20s seeking help to conceive. According to Dr. Bushra Khan, Fertility Specialist at Nova IVF Fertility, Kharadi, Pune, this shift is both real and concerning.

“Until a few years ago, fertility problems were mostly age related. Today, we are seeing women between 23 and 29 struggling to conceive,” she said. “Many assume they are too young to have fertility issues, so they delay medical advice.”

Experts say modern lifestyle factors, stress, and untreated health conditions are affecting reproductive health earlier than expected. The encouraging part, however, is that early diagnosis and treatment can significantly improve outcomes.

Common Fertility Issues Seen In Young Adults

In women, doctors frequently diagnose polycystic ovary syndrome, ovulation disorders, thyroid imbalance, endometriosis and pelvic infections. Some also show poor egg quality despite being in their 20s.

Men are not unaffected. Low sperm count, poor sperm movement and hormonal imbalance are becoming increasingly common. Obesity, smoking, alcohol consumption and prolonged laptop use that increases heat exposure can affect sperm health.

“These problems require timely evaluation rather than waiting for years,” Dr. Khan explained. “Early intervention keeps treatment simpler and more effective.”

Lifestyle Is A Major Contributor

Unhealthy diets, lack of physical activity, high stress and disturbed sleep patterns play a major role. Increasing obesity and insulin resistance among young adults also interfere with ovulation and sperm production.

Pollution and untreated infections further complicate reproductive health. In some cases, genetic factors may also contribute.

“Fertility health reflects overall health,” Dr. Khan said. “What we eat, how we sleep and how stressed we are directly impact reproductive hormones.”

Warning Signs Young Couples Overlook

Many young adults dismiss early symptoms because they believe infertility affects only older individuals. Doctors advise not ignoring the following:

• Irregular or painful periods
• Acne and excess hair growth
• Sudden weight gain or loss
• Persistent fatigue
• Low libido or erectile issues
• Difficulty conceiving after one year of trying

“Fertility issues are now being detected even in people aged 20 to 27,” Dr. Khan noted. “Ignoring symptoms can worsen hormonal imbalance over time.”

Risks Of Delayed Treatment

Delaying treatment may reduce egg or sperm quality and increase emotional stress. Couples may later require more complex procedures.

“Seeking help early improves both success rates and peace of mind,” she added.

How Assisted Reproductive Technologies Help

Assisted Reproductive Technologies such as ovulation induction, intrauterine insemination and in vitro fertilization are highly effective in younger patients because egg and sperm quality is generally better.

These treatments help conditions like PCOS, blocked tubes, severe male factor infertility and unexplained infertility.

Egg freezing is another option that allows women to preserve fertility for medical or personal reasons.

“Egg quality declines after the mid 30s. Preserving eggs earlier gives women reproductive flexibility,” Dr. Khan said. “The most important step is awareness and timely consultation.”

Doctors stress that fertility awareness should begin early. Monitoring symptoms and consulting a specialist promptly can prevent complications and significantly improve chances of conception.

Seeing your child suddenly screaming at night, with wide eyes and thrashing limbs, can be deeply unsettling. However, remaining calm and focusing on safety is crucial for parents during the sleep terror episodes, said health experts.

Sleep terrors, also known as night terrors, are episodes of sudden fear, screaming, or intense distress that occur during sleep.

The condition is more common in children, especially between the ages of 3 and 8 years, as their sleep patterns are still maturing.

Unlike nightmares, which usually happen during dreaming (REM sleep) and are often remembered, sleep terrors occur during deep non-REM sleep.

Dr Preeti Singh, Senior Consultant, Clinical Psychology, Max Super Speciality Hospital, Dwarka told HealthandMe, that while it may be frightening to witness, especially for parents, sleep terrors themselves are usually not harmful.

Although most kids outgrow this naturally, if the episodes are violent or very frequent, consult a specialist, added Dr Sudhir Kumar, a neurologist at Apollo Hospitals, Hyderabad.

What Are Sleep Terrors

During sleep terror, the child may sit up abruptly, shout, appear frightened, sweat, breathe rapidly, and be difficult to console. In most cases, they do not recall the episode the next morning.

Sleep terrors typically occur in the first third of the night, during deep sleep (slow-wave sleep). They are considered a type of parasomnia, meaning an unusual behavior during sleep.

Dr Kumar, in a post on social media platform X, explained that unlike a bad dream, a sleep terror happens in deep sleep (Stage N3).

It is characterized by abrupt sitting up/screaming, with physical signs that include a fast heart rate, sweating, and dilated pupils.

"It is 11 PM. Your child suddenly sits up, screams at the top of their lungs, and looks terrified. They are not responding to you, and they seem to be looking right through you. This is likely a sleep terror (night terror), a common NREM sleep parasomnia in children aged 3-12,” said Dr Kumar, popularly known as the Hyderabad doctor, on X.

The expert noted that the children are unlikely to recognize the parents and be "consoled" during the episodes.

What Factors Trigger Sleep Terrors

• Sleep deprivation or irregular sleep schedules
• Fever or illness
• Emotional stress or anxiety
• Major life changes or trauma
• Family history of parasomnias
• Certain medications

For children, sleep terrors are often developmental and tend to reduce as the nervous system matures, Dr Singh told HealthanMe.

How Can Parents Respond?

Parents often feel alarmed during a sleep terror episode, but the key is to remain calm, the experts said. They said during an episode:

• Do not try to fully wake the child, as this may increase confusion and agitation.
• Gently ensure the child is safe and cannot injure themselves.
• Speak softly and reassuringly, even if they do not respond.
• Wait for the episode to pass, which usually happens within a few minutes.

Other preventive measures include:

• Maintaining a consistent bedtime routine
• Ensuring the child gets adequate sleep
• Reducing screen time before bed
• Managing stress during the day
• Creating a calm and secure sleep environment

How To Manage

Most children do not require medical treatment, as sleep terrors usually resolve on their own with age. Treatment is considered when episodes are frequent, severe, cause injury, or significantly disrupt family life.

However, addressing sleep deprivation, treating any underlying medical conditions (e.g., sleep apnea), counseling or stress management strategies can help.
