I have a 4 week old daughter who is breastfed. She occasionally uses a dummy and I have expressed a few bottles of milk which she accepted. We want to give her a bottle of expressed milk each night so DH can do a night feed. However, I'm really confused how much I actually need to be expressing as I'm worried if say my mum babysits her for a few hours she'll run out of milk. Do I just empty both boobs as she normally does that in a feed? Or is there a specfic amount I should express?
I'll add she is really healthy and gaining weight well
