Ay, common yan sa newborns, lalo na kung mainit! A few of us nag-experience din, sometimes it's heat rash o baby acne na mag-disappear lang on its own in a few weeks. Best thing is mag-check with your pedia to be sure kung anong type ng rash kasi may iba't ibang causes, tapos makakaadvice sila ng proper care depending sa ano talaga ang situation ni baby.
