1. Intense Struggle With Ordinary Activity
All children have a different developmental pace and personal traits too. Some take to concepts of sociability, playing, hygiene, etc. faster than others. Others may be slower learners. However, if you find your child to be struggling with all kinds of ordinary activities, you should begin being more observant. If there seems to be no improvement in your child’s adeptness at understanding/accepting concepts despite repeated emphasis, he could be autistic.
