Sorry for my ignorance but what is BFAR? I'm a BFing and expressing mumma - I do wash the pump parts but mainly because I like to steralise each and every time because I think I get more milk when they are warm With your bub being so young, your supply is still establishing so in my opinion, if you want to get a good supply you should be resting as much as possible and also not missing feeds/expresses. Why don't you just BF your DD during the night and then express afterwards if you don't feel like you are fully drained? It's just one feed and it's not like you are missing a feed? If you do want to feed/express I would feed on one side and express the other at the same time. It's easier if you have an electric pump and quick too because as DD gets your letdown, it makes easy work on the expressing side. This will sound ridiculous but I found the easiest way to express and feed was to slouch in bed with a pillow behind me and prop my knees/legs up so DS was lying in that groove and I could just support his head with my one arm and hold the pump with the other.
