What is engorgement?

Pumping glossary; plain language, no fluff · Updated July 2026

Quick answer: Engorgement is the painful overfull swelling, milk plus tissue fluid, most intense when milk first comes in (days 2 to 5) and during abrupt schedule changes or weaning.

In practice

Relief is gentle and cyclical: brief warmth or a shower before removing milk, remove to comfort (a nursing baby or a few minutes of pumping or hand expression), then cold packs to calm swelling. Removing only to comfort, not to empty, keeps relief from becoming an oversupply order. Fever or a hot red patch escalates it to a provider call.
