Ay, nakakababa talaga pag may rashes ang baby, hindi ba? A week is quite a while na, I'd really suggest checking with your pedia soon kasi maraming types ng baby rashes at need talaga ng proper diagnosis kung saan exactly at ano ang cause (heat rash, fungal, allergy, diaper rash?). A few of us moms sa circle namin, iba-iba ang nangyari sa babies namin, one was ammonia burn na, one was heat rash from the weather, kaya talaga kailangan ng professional look. In the meantime, make sure the area is clean and dry, pero best pa rin ang doctor to rule out anything serious at get the right treatment para mabilis mawala!
