Mama, I'd really suggest checking with your pediatrician or midwife about this kasi it's better to be safe, lalo na ganito kalaki ang baby mo pa lang. A few of us moms have had babies with white stuff on the lips too, and sometimes it's nothing, pero kailangan talaga i-confirm ng doctor para ma-rule out any concerns, mas peace of mind lang para sa inyo! Let me know kung ano sabi ng doctor, ha.
