wala naman pong exact na tamang buwan basta po advisable wag mag-apply during the newborn phase kasi nagdedevelop pa po ang babies ng natural skin protective barrier. in my opinion naman po 4 months and above tingin ko ok na. make sure hypoallergenic and alcohol & fragrance free po ang lotion, also magpatch test po kay baby bago iapply sa buong body. But always best to consult your pedia po before applying anything kay baby hehe
