Just a note, my biggest baby was 10p14 and 000 we're big on her in hospital too, you wouldn't think so She wore 000 at least for the first few months.
I'm taking in outfits for this little one, all ooo. at least 2 for each day including socks and singlets and a couple of jumpers and a hat for going home.

Me I'm taking casual clothes, tracky dacks, t shirts, and a jumper - pj's and dressing gown for night and bed socks and slippers

Take care now
