I'd get more sleepsuits (long sleeved with feet and, if you can built in scratch mits). My ds got through 3 during the 22 hours he was in hospital!! Maybe another couple of cardigans? You don't mention bottom sheets for the moses but you'll need a few of those. No need for toiletries but you'll need cotton wool- the pads are better than the balls. All in one snow suit type thing for outdoors and transfer home. Nursery thermometer Bouncy chair Moniter
I agree with more sleep suits, we went through a few a day when our baby was newborn (and she is 4 months and on her second of the day today). We did get lots as hand me downs and gifts though so might be worth holding fire.
I would look into cot bumpers, there's a lot of literature out there about them being dangerous. Our baby is not in a cot yet so not even considered them but I think people uses something called an air wrap instead?
We use a bath rest so she doesn't need a whole baby bath to herself, we chose this purely for space reasons.
I used muslins for swaddling my little one when she was tiny. It really helped us because she used to wake herself up by flailing around and is one of the few things I will be buying yet more of for no2.
