@nursebickypegs I'd personally not pack either formula or a breast pump in the hospital bag if you want to try bf.
Expressing at first is probably a bad idea unless you need to because your supply is being established, and unless baby can't latch or needs topping up you risk either having over or under supply. If you do need to pump the hospital should be able to assist with a hospital grade pump in the meanwhile. The best idea is loads of skin to skin and letting the baby suckle as often as it wants (and if it hurts when baby does that, getting help asap to check latch and so on).
Packing formula is almost like admitting defeat before you'e started IMO (unless you're sure you want to ff or mixed feed from day 1). If you do want to pack some, it's worth checking your hospital's policy on formula. Some insist you provide your own, and some insist that if you do provide your own it's the carton stuff not the powdered stuff.
Realistically, I'd not try expressing (if all is going well) until at least two weeks post birth, probably more like a month. The first two weeks with a newborn - you should expect to do nothing else (nothing!!) aside from recover from the birth (even if you had the most fantastic birth ever, your body is still dealing with a shedload of changes and hormones!), get used to the new baby, feeding / sleeping / changing the baby. Don't expect to do any housework or cooking whatsoever (anything you do get done is a bonus). It gets easier after two weeks, quite quickly. And yes, almost anything is 'normal' regarding baby feeding - some like a massive long cluster feed in the evening (if they do this you may be lucky and have them sleep a bit longer at night!). At first you're literally feeding / changing / getting baby to nap and then the cycle starts again.
