Hi mummies. Im a FTM.. spotted these small rashes on my 10 wks old baby's neck. Is this heat rash or allergic reaction? He dont seem bothered by it though. Thanks in advance!

it's heat rash mummy. these rash are usually cause by sweat as it's in between the skin folds. you can clean with lukewarm water. wipe dry. i always apply lotion for bb in that area too
