T.O.
My 16 year old has Asperger's..... which could be the same thing as PDD NOS.... there seem to be new names all the time for the same thing.
Anyway, being a toddler wasn't too bad for us. He would play by himself and with others, but that usually didn't go well because they didn't want to play like he wanted and he'd get frustrated. But we did have lots of play dates.
He was over-focused on the computer when he got into that at age 5. He'd forget or choose not to go to the bathroom and wet his pants while he played computer games. You couldn't pull him off. It was like a drug.
In general, it was easy to handle him, though he would forget instructions (he still can't handle more than 3 directions at a time "go to your room, get your shoes, put them on"). When he was younger 1 direction was often too much and we'd have to repeat it over and over. But it got better.
He didn't like loud noises and would freak out sometimes. He still doesn't like them but he's learn to tolerate church music etc.
