What are all the important things to buy for the baby before she comes?

boppy pillows are a wonderful convenience. as far as diapers go you never know how long a baby will be in a certain size, but if you want to stock up you can get 2 packs of newborn to start with and you can always buy other sizes in advance. my son is almost in a size 2, and we have 3s and 4s, just because we had some extra money and found a good sale. with bottles, don't buy too many of a certain kind, because the baby might not like them. if you will feed and bottle feed you should get wide . sounds like you have a good start on things... good luck with your baby, and enjoy every minute!
