Mastitis (Breast Infection While Nursing)
A painful breast infection during nursing — keep nursing, apply alternating hot/cold compresses, rest completely, drink plenty of fluids, and see a doctor if symptoms don't begin to improve within 12–18 hours.
📝 Summary
In short: A painful breast infection during nursing — keep nursing, apply alternating hot/cold compresses, rest completely, drink plenty of fluids, and see a doctor if symptoms don't begin to improve within 12–18 hours.
Common causes: Bacteria (typically staphylococcus) entering through a cracked or fissured nipple; Incomplete emptying of the breast during nursing — stagnant milk supports bacterial growth; A blocked milk duct not cleared promptly.
First thing to try: Do NOT stop nursing. Continue feeding on the affected breast as often as possible — the milk is safe for the baby and nursing clears the infection faster than stopping.
See a doctor if: Symptoms don't begin to improve within 12–18 hours of careful home care

- Ensure the baby is positioned and latched correctly — shallow latching is the leading cause of nipple cracking and subsequent mastitis.

Favor these

- Garlic for its natural antimicrobial properties
- Probiotic-rich foods — some evidence suggests probiotics may support resolution of lactation mastitis
Go easy on
