Does Breast Milk Go Sour In The Breast?

No, breast milk never “spoils” or goes bad while it’s inside the human body. Your breasts are amazing regulators!

Breast milk is a living substance and is continually changing inside the breast to keep it fresh and perfect. 

In fact, freshly pumped breast milk is so full of protective factors that it takes awhile to go bad outside of the body. (approximately 4 hours at room temperature)

What Happens If You Wait Too Long Between Nursing Sessions?

If you wait too long to nurse between sessions, the milk won’t go bad inside your breast but you’ll probably start to feel engorged.

Breast engorgement happens when too much breast milk accumulates in the ducts.
