My 3 year old is on the spectrum and as he has gotten older it seems he is developing more sensory issues.
Like before he didn't care if his hands were messy. Now they can't be messy at all. He didn't mind sand before, now he doesn't like to touch it. Same with playdoh, no problems before but now he doesn't like it.
I also notice him getting overstimulated more and more. Lately it's been lights. He will say his eyes hurt. Sometimes it gets so bad he throws up.
Is that typical, for a child to throw up when they are over stimulated? Sometimes he just has a meltdown but sometimes he throws up.
