What is breast engorgement?

Breast engorgement is when your breast tissue overfills with milk, blood and other fluids.

When your baby is born, your breasts are given a signal to start full milk production. Your milk usually comes in 1 to 4 days after your baby is born. Breast engorgement is quite normal in the first few days after your baby is born.

Breast engorgement can also happen at any time when you are breastfeeding, especially when your baby’s sleeping or feeding patterns change and they feed less.

If your breasts continue to feel overfull beyond the first 4 to 6 weeks, you may have an oversupply of breastmilk.
