My son will be turning 3 in May, he doesn't talk. All he says is babble "mama", "knack knack" (when he sees a duck/bird) and "anana" for banana.
He hums to songs a lot, dances, gets excited and shakes his arms in front of his face, squints his eyes, spins, scuttles around stomping his feet close to the ground if that makes any sense, sometimes he will run on his tiptoes. He is good at pretend play and likes other children, he is very confident and will adapt to his environment very fast (if there are toys in a new room he's never been to, he will just play with them straight away), he waves, smiles at people and blows kisses. but he does display some more autistic traits like lining up his toys, covering his ears with his hands, parallel play, echolalia, he doesn't point, etc...
He gets very frustrated, throws things on the floor, hits me, his dad, and his baby sister. Screeches.
He doesn't listen to "no". He will try to climb on the kitchen counter to reach the boiler again and again and again obsessively.
His vocabulary is quite limited, he doesn't understand many instructions and doesn't know many words. He doesn't know what yes and no means.
He's also a VERY picky eater.
How likely is he to start talking if he's non verbal at almost three?
His speech therapist said she thinks he might have autism.
I don't know where to go from here.
