Rash

It might be teething x

Could be a rash from milk going into they’re neck

My baby always gets these maybe a little bit of sweat/heat inbetween he’s neck and chin x

Looks like dribble rash , keep it dry xx

Looks like it’s a rash from being wet from drool/sweat and maybe milk as milk runs down their neck a lot at that age xx

Heat rash

Heat / dribble rash, please see your doctor and have something for it. My daughter is 8months she had this n initially i applied breastmilk / zerobase lotion etc , thinking it would get better, it hot worst and now my baby cannot sleep whole night due to itching and crying and restless. although its nothing that can harm them but make them restless.
i'm going through this thats y explaining you. 🫥
