World Autism Awareness Day is observed on April 2 every year, a day to spread awareness about autism, its causes, symptoms, and what parents can do to help their children. But even when it comes to autism, there is a great deal of prejudice surrounding the disorder, which often forces parents into a state of denial. A condition which initially comes across as a personality trait—shyness, for instance—is usually diagnosed late. Dr Hamza Hussain, Head of the Department of Psychiatry and Mental Health at Ruby Hall Clinic, Pune, in an interview with Health and Me, explained how parents can spot the signs of autism early in their children.How to know if your child is autistic or just shy?It is completely understandable for parents to feel worried when they notice delays in their child’s speech, social engagement, or behaviour. That said, it is important to recognise the differences between early indicators of Autism Spectrum Disorder (ASD) and other developmental patterns or conditions.Read more: World Autism Awareness Day 2026: Can Cell Therapy Be The Future Of Autism Treatment?Children who may be on the autism spectrum often display ongoing difficulties with social communication and interaction. They might avoid making eye contact, not consistently respond when their name is called, show delays in speech, or find it challenging to engage in two-way conversations. Repetitive actions—such as hand movements, arranging toys in a particular order, or insisting on strict routines—can also be early indicators. On the other hand, children with ADHD are usually more socially responsive but may struggle with focus, impulsive behaviour, and high activity levels. A speech delay alone does not necessarily point to ASD, especially if the child shows good non-verbal communication like gestures, expressions, and social interest.What are ASD patterns?One important way to tell the difference is by observing patterns over time. Signs of ASD tend to be consistent across different situations and environments, whereas other behaviours may change depending on the child’s mood, surroundings, or level of stimulation.Support at home plays a vital role in a child’s development. Simple, consistent interactions can go a long way. Spending time in face-to-face play, encouraging eye contact, and talking through daily activities can strengthen communication skills. Reading stories, singing rhymes, and using gestures can further aid language development. It is also helpful to limit screen exposure, as too much screen time can impact attention span and social learning.Read more: Why Autism In Women Is Often Overlooked And MisdiagnosedHow can parents help?Having a structured daily routine can help children feel more secure, while encouraging and praising positive behaviours can reinforce learning. Above all, recognising concerns early and seeking timely intervention can significantly improve outcomes. If parents feel uncertain about their child’s development, consulting a professional early on can provide clarity and the right support for the child’s growth.
