my girl is 5 months old and has had heat rash for nearly a week now, we are trying to keep her cool and have a fan on in the house through the day and night. she has no other symptoms and hasn’t had a temp at all, but the little spots are all on her arms (worse on right as as contact naps still and that’s the arm she sleep on), neck, a few on her back, on her chest/belly and in her hair on her head. should i take her to the gp on monday? how can i try help her in the meantime, im just so lost
