Aww, I feel you mama, sobrang nakakaalala yan especially pag ganyan bago pa lang ang baby Sa age na yan, kailangan talaga ma-check ng doctor para sure kung ano type ng rush, pwede kasing heat rash, milk allergy, or eczema kaya really important na ma-assess ng pedia mo ng maayos. One of my mum friends, her baby had similar rashes at 2 weeks and turned out sensitive lang siya sa detergent, kaya pinalitan nila ng gentle baby wash, pero honestly best move is to have the doc look at it first para ma-rule out kung may infection or something, okay?
