DS is 3.6 and his speech/communication is good, has been since he started talking.
He still repeats back a fair amount, though because he talks SO much, it's probably only a small fraction of his overall speech.
He doesn't do the typical "ASD" echolalia that I've read about eg if asked a question "do you want a drink" or a more complex, open ended one eg "what was your favourite thing at the park" he will always answer appropriately. His echolalia is more statements eg if I say it's a lovely day, he'll repeat that. He sometimes changes it up a bit so it's appropriate/in the right context eg if I say it's a lovely day DS name he'll say it's a lovely day mummy. But he doesn't respond how you would expect an adult to eg "yes it is" or just "yes". Or often if I say I'm cold he'll say I'm cold too.
He also does it more so with new (ish) people, so if his little friend is over, and he says let's go outside and play on the trampoline! DS will repeat it.
Is this normal? Does anyone else's child do similar at this age? I haven't noticed other children doing it, really.
