Peter's seven and he's just as comfortable fully clothed (well, except on picture day) as he is walking around stark-naked. I don't mind him sleeping naked in the privacy of his bedroom. Although it is a bit awkward when I check on him at night and see the silhouette of his bare butt raised in the air to greet me, highlighted by only his Avengers nightlight. My problem is that modesty hasn't come with age.
He doesn't have an aversion to clothes or even underwear. It's just that he loves stripping down when in the comforts of home. He used to return from preschool and get naked the second he came through the door, before burying himself underneath a heap of all of his special blankets. He was three and autism was new to me. I just figured it was a phase he'd outgrow. But here he is in the second grade and he's bouncing around unaffected that parts of his physical body need to be covered, not only for sanitary reasons, but to follow the rules of appropriate decorum.
I guess it relates to the uninhibited part of autism. The part that calls people fat, my cooking horrible, and his teachers old. The part that addresses people by their nationality and mixes up the names of his grandfathers (the biological vs. the one by marriage). The part that tries to look up my skirt and tug on my pants. The part that's curious about his body and wants a peak at everyone else's. The part that prefers peeing outside instead of in a toilet. That's a whole other issue.
The optimist in me is thankful that Peter is no longer getting naked in front of non-family members. The pessimist in me fears that, even if he does start covering up, puberty is just around the corner and just might reignite his curiosity all over again.
