13 month old used to make less eye contact, rare smiles and not responding to name otherwise he is good eater and sleeper, playful, shows some gesture through his hands. But as per pediatrician he was having low blood and need to reduce screen time which we did and hence he improves with eye contact and smiles when we are in the front of him. But still not responding to name. My concern is does cow milk, sooji and daaliya trigger Autism symptoms?
