whar doea this look like to yall it popped. up over night

I'm thinking pupps rash are you having a boy?

It looks like a heat rash but I'm not sure...my daughter was like that alot after she was born and at 1 still get like that do to heat rash

I had it when I was pregnant it eventually went away

Okay is this your baby? Or is it you?? If it's the baby heat rash or a rash from an allergic reaction

my son

its all over him. but that spot and neck one is really standing out. his doctor told me before he might has contact dermatitis. but thst dont look like it

my daughter gets that if her clothes get washed with tide by accident
