I worked out that a last off/first on method worked best for me so I'd never fully drain both breasts at the feed, but the one that wasn't drained was the first one bub went on for the next feed. There is no need to feed stupid hun! What is one nurses opinion of how it should be done is not necessarily the right way for you.

At 6 days your breasts are still working out what to do so there is a chance of lumps regardless of them being fully drained. It's not ideal to leave one engorged though so if that is happening then express the edge off.
