My baby nurses to sleep all night. Does milk staying in her mouth harm her teeth, and how do I prevent decay?

Nursing or bottle-feeding all night, especially once teeth start coming in (usually from 6 months), increases cavity risk. Milk staying on teeth overnight lets bacteria feed and produce acid. This is called "bottle rot" but applies to nursing too.
To prevent it, you can try:
- After the last nighttime nursing, gently wipe baby's mouth and teeth with a clean, damp cloth or finger brush.
- Encourage baby to fall asleep from soothing (rocking, holding, books) rather than nursing, helping her transition to sleep without food.
- At night wakings when you do nurse, gently remove the breast once baby drifts back to sleep.
Start dental checkups when the first tooth appears or by age 1 — your pediatrician will guide you.
