Good question- wish I'd have know a bit more beofre I had my baby.
My baby was 4.2kg/9lb 5oz and 51cm long and only fit into 0000 in hospital and maybe a week after that at most (so, 2-3 weeks all together). One other piece of advice to be mindful of- the Bonds brand tends to run extremely small comparted to other brands.
I didn't but too much clothes ahead of time (we didnt know the gender) and ended up getting so much clothes as gifts that I think I would have had more than was wearable if I had purchased a lot before.
