Son stripping off clothing, what is that?!

[Guest guest]

Hi everyone.

My son is five with autism diagnosis. Lately (and he has done this

before a year or two ago) he has been stripping off all his clothing and nappy

too overnight and several times a day. His doc said it could be Pyrolles.

He gets agitated if I don't let him strip.

I use a decent washing powder(hypoallergenic) for his

clothing etc and havn't used anything new.

He also has had an aversion to wearing his sandals for the last few

months. Has anyone had this experience or have

any ideas what it may be?? And how to resolve?
