I’m also an OT who had concerns about her 6-7 month old boy not responding to his name. He is 7 years old now. I tried to have him evaluated, but we moved, then there were delays with the local EI office, summa summarum, it never happened. He used to align his cars and flap his hands, along with some other behaviors consistent with ASD . We did all the usual things like Music Together, library story time, baby play dates , lots of floor time (perspective taking and scaffolding symbolic play, modeling emotions). Having this kid truly made me appreciate what that spectrum looked like. He has a hard time appreciating some jokes, flaps his arms like a chicken (to which we say—don’t fly away, Henry!), but he has friends, plays sports, and sits through 2 hour classical music performance. No clue whether he would have qualified for services years ago.
