My 17 month old doesn't respond to name, nor smiles back but he does ask for things with gestures. Like he gives us remote to start Tv or to change song, also ask us to pick him up by raising his hands. Eats well almost everything. sleep well superactive. His pediatrician told us may be iron deficiency also suggest audiogram but he listen even small sound of packet if open behind him. No repetitive actions. Knows his family members through face. Will he develop autism or he will be ok after some months or year.?
