Autism and Clothing
When you have autistic children, you are likely to come across all sorts of oddities with clothing. Common quirks include chewing or sucking on sleeves, having great discomfort from elastics and labels and wanting to take their clothes off. And then of course, there is that embarrassing habit of touching their genitals.
One tip I keep hearing from parents of children with autism is that their kids find it much more comfortable to sleep in one piece pyjamas. It may well be the lack of elastic around the waist, since the belly seems to be especially tender for many with autism.
They can be hard to find though, so it you find a supply, stock up. Clothing designed to meet the quirks of autism can make night time much more comfortable.
