i'd recommend loads of breast pads and maternity pads. also, i found that i preferred in the early days to have the big fat squishy pads over the libra thin ones that i bought as the extra cushioning can be a bit more forgiving on the tender post-birth regions IYKWIM

another tip i have is to get a bra that is one cup size bigger than what you are as sometimes when the milk comes in the engorged boobies can be rather large (i had to send DH off with MIL to get a 12e - i was a 12d at that stage). i used the bigger bra until they settled down...

hair brush and some lip gloss never goes astray in case of photography emergencies! LOL!

and a nice 'visiting hours' nightie...
