Don't overdo the clothes. Mostly people will give you 0000 & 000 clothes. Just get enough to have at hossy. Before you've given birth you will have more than you need and then you'll get more when you get home afterwards.

IMHO you def don't need a rocking chair. I know some swear by them but I already had one and haven't used it once.

Get lots of flannel bunny rugs that are large enough to line your basinette, cot or rocker in case you have a chucky baby. This way you only have to replace the bunny rug several times a day instead of having to constantly wash the cot or basinette fitted sheet. I got mine at Safeway I think - 3 for $10.

Try not to buy too much as you will be given heaps of stuff.

Must haves are:
cot and or basinette
change table or change mat
bath (mine is in the change table) - to save your back
facewashers
bibs
hat
all in one suits which have the mitten cuffs on them
singlets or even better short sleeved all in one suits without legs - singlets can get caught in the nappy and then cause a wet back
nappy stacker
set of drawers
something to put nappies, wipes bags, lotions, facewashers, nappy rash cream etc in that you can put next to your change table. I've got a 3 tier open shelving thingy that's on wheels. I just keep a few nappies and all the other stuff there so I don't have to walk away from bubs.
