Go to a doctor now if: Persistent cracked mouth corners with pallor/tiredness (possible deficiency), spreading rash around the mouth, bleeding/infected cracks, or symptoms not improving — see a doctor.
Food-first comfort
(Lip care) Coconut oil/ghee/plain lip balm; discourage licking. Diet: B-vitamin and iron foods (dal, egg, greens, whole grains, curd), vitamin-C fruit, and plenty of fluids — cracked mouth corners can signal B-vitamin/iron shortfall.
What to nourish
B-vitamin/iron foods (whole grains, dal, egg, greens), curd, hydration.
Never
No medicated adult lip products for young kids without advice. Don't ignore persistent sore mouth-corners (may need iron/B-vitamin review).
Care at home
A simple barrier plus a B-vitamin/iron-rich diet and hydration heals most chapped lips and mouth-corner cracks. Persistent cases hint at a nutrition gap worth checking.
