Buy clothes in 0000 and 000
Muselim wraps are good - We still wrap our bub in them when she goes for a sleep
I also recommend that u buy a tin of formula just incase u can't breast feed or u dont have enough milk etc and u need to top bub up, cause garunteed it will be the middle of the night when nothing is open and bub is screaming cause he/she is hungry!
do u have a baby bath? u dont really need one, but helps if u dont want to be leaning over the big bath!
Are u going to use cloth or disposables?
Buy a few bottles and a dummy just incase
A breast pump is also good!
They are just some ideas - hope that helps a bit
