Mommy, this is something na kailangan i-check ng doctor agad, hindi ko ma-confirm kung normal ba yan or something else na kailangan ng treatment. Please bring baby sa pediatrician or nearest clinic, lalo na kung may ibang signs like baby's having trouble feeding or may fever, then go to emergency na.
A few of us moms have had concerns about baby's skin changes, at ang safest talaga is to let the professionals look at it in person. They'll know right away kung ano yan. Fingers crossed it's nothing serious!
