I would only buy one bottle, just for emergency use.
Breastpump, even just a simple hand model, to ehlp with engorgement or get a freezer stash going.
A sling is a must-have - I prefer wrap styles.
I don't use any bath products at all, but vaseline can be useful.
Tons of baby wash cloths and burp cloths - even if you don't use them all straight away, you will eventually
Lots of little socks and hats for a winter baby.
Um, that's all I can think of...
