N.P.
My now 10 yr old was like this really bad as a preschooler, and my 13 yr old not so bad. Almost all the daycare kids are to some degree like this when the weather requires the change from long to short or vice versa with clothing.
I am irritated that the modern way of handling this is to assume a disorder of some sort. How bout a kid just not liking how something feels? Or being a kid and exerting some independence?
Honestly, just tell the kid, tough, or let them deal with the consequences and let it go. If the child goes to a school enlist the teacher for help - I have had to email my younger daughter's teacher and say, "can you tell the class that coats, hats and mittens are now required every day?". And guess what - she gets over it and each year it's a bit less. Now that she is older I know to make her try on every clothing before we buy it, I know she doesn't like collars around her neck or lace anywhere it touches the skin. But this does not make her having sensory disorder. It just means she is normal. Do YOU like every clothing you have ever tried on??
Let it go. Stop concentrating on it. It's really not that big of a deal.
