Oo normal lang yan, lalo na sa darker-skinned babies, ang lip color nila ay naturally darker pa rin habang baguhan pa lang, and it usually evens out after a few weeks or months as their skin settles. A few of us mums noticed the same thing sa aming babies at medyo nag-alala kami din, pero the pediatrician assured us it's totally fine! Pero kung mukhang unusual na sobrang dark or may ibang changes, worth checking with your baby's doctor lang para peace of mind mo.
