How do I teach my child to......?

[Guest guest]

How do I teach my child to answer a question of " Why did you.....? "

It's so frustrating when he won't answer questions. He is 3.5YO and we

have just recently been able to get him to answer " yes " or " no " to

those type questions - and it's not even all the time, just

sporadically.

For those who do not recognize me, I am a newbie on here. My son has

not been diagnosed yet (and so we are not receiving any help yet) but

we, his parents, know that he is definitely somewhere on the spectrum.

TIA
