The milk comparison is between breasts. Left breast is always fuller and bigger. This milk that I froze is rich creamy and even coloured. Right breast is always the less full, not able to do a full feed side. When I've expressed and frozen this side it is more watery looking with a creamier centre. Definitely not as rich as the left side.

I'd always known dd doesn't get full on the right side, I normally just top her up with it to sleep now. I'd always just thought it was the quantity, but it appears the quality or creaminess is different too.

It was a full express from both sides, same time of day.
