Take him to the doctor ??

My son came home from daycare with this Thursday on his fingers. At first I just thought it was glue. He didn’t have school on Friday so I never got to ask and they’re off again on Monday

What does this look like to you ?? My mom said it looks like a fall from outside - but Thursday it snowed here and I know they weren’t outside.

It’s on BOTH his hands and just on the fingertips.

I think it looks like burn marks. My husband says dry skin - but only on his fingertips? And appearing suddenly after school ?

I don’t want to rush to the doctor for every little thing ... help me out please !

Sorry these are the best pics I can get
