I’m concerned about my 12 month old baby. He walks, can feed himself, drinks from a cup smiles at others, plays excitedly with other children, babbles sometimes and giggles a lot when I play peek a boo. He reaches out to be picked up. He started pointing some time ago with his finger when he wasn’t walking but stopped doing that and now occasionally uses his hand to gesture when encouraged. He does respond to name but some days more than others. When playing with him he is inquisitive but doesn’t give much eye contact though he will look back over his shoulder now and then for reassurance. He will play with lots of toys but doesn’t seem interested much in sharing toys and will move on to something else quite quickly. I haven’t been able to get him to give a toy back willingly yet. When reading a book to him he has a short attention span and won’t point to things. He sometimes will follow my hand when I point to things but doesn’t look back at me once he has seen it instead just squirms to get to it when I’m holding him. He has copied sometimes e.g. clapping, putting out tongue, banging objects together. He doesn’t copy sounds directly. He will occasionally fetch a ball and throw it when asked and seems to understand no (though not all the time and he cries sometimes when I say no to something he knows he shouldn’t do). I’m worried about red flags here and asking you what you think....
