Baby sensitive skin?

Amarillys/22🧚🏻‍♀️

My baby’s skin has been like thei for a while I can’t remember how long she’s had it but it has been for quite some time she has like dots on her legs and arms not really her stomach but a little on her neck and she also has baby acne on her face is it possible this is baby acne or something else? My pediatrician said it was normal but I never seen anything like that her skin has texture on it could it be a fabric thing?
