Kate - Geelong hospital provided all the bath lotions etc. while we were there so I didn't take any. I did take clothes to put Gabby in though because I don't like the little gowns that they have there. I still used their nappies tho! Also, as far as lotions go, they don't really need them for the first few weeks because they have their own natural oils taking care of their bum. It's preferential, of course, but I still don't put a great deal on Gabby's bum except a little powder every now and then. She hasn't had a rash at all so far. In hospital they provide cotton balls for you to wipe their bottom with. Once I got home, I used a face washer (with warm water) for pooey bum.
Hope that helps!
