Are breast pain, hard lumps or milk stasis during breastfeeding normal, and when should you see a doctor?
Applies to age: 0–12 months
In short
With milk stasis (a lump in the breast) or mastitis, contact a midwife as soon as possible. Engorgement between day 3 and day 5 after birth is a physiological, normal state; breastfeeding should not hurt.
What is normal
- Breastfeeding should not cause pain.
