My son is almost 3, we've known he was not neurotypical since forever. He is developmentally on track but he has a lot of sensory needs and his behaviour is extremely challenging. We are at the point of pushing for ASD assessment and gathering evidence.
One of the things I’ve noticed he does when meeting new people or when feeling anxious (e.g at his recent nursery settling in session) is he will go into show off / performance mode and pretend to do super hero poses, like he will say “spiderman webs” and pretend to fire webs and he will continue making other superhero stances. He won’t answer to his name in this time and he will continue for quite a while. Another thing which is similar is, he will purposefully fall over - because he knows people will gasp and say “are you ok!?” etc. he does it all the time in front of old ladies in the supermarket.
I apologise if this is a ridiculous question but I didn’t recognise echolalia until quite recently and its got me thinking about this behaviour.
