Using pillow as blanket

cassi

So I'm dying to know, does anyone else's toddler basically use their pillow as a blanket? My almost 2 year old will not use a blanket. He takes his pillow and puts it on top of himself and goes to sleep like that. Every single time he sleeps. He even pulls his pillow out of his bed and will put it on top of him on the floor lol does anyone else's kids do this?

We are getting him tested for autism so I don't know if maybe it's an autistic thing? Like sensory or compression? Here's a picture of what I mean haha ignore the dirty floor, they(my almost 3 year old and almost 2 year old) absolutely destroyed their room so I hadn't cleaned it yet
