When my youngest was born she was only just other 5lb, I didn't have any tiny clothes.
Yes the new born clothes were a bit big but they did until we left hospital and oh could get a few bits for her.
I have 5 vests and 5 sleep suits,a going home outfit,two cardigans and a jacket and two blankets for baby,two hats,bibs.
Travel size shampoo,shower gel,toothbrush and toothpaste.
Lip balm,deodorant,comb.
Pack of nappies,pack of wetwipes.
Going home clothes for me,oversize nightly to have baby in.
Two dark pairs of pj's,socks with grips on.
2 packs of maternity pads.
A plastic bag to put any dirty stuff in is always handy to separate.
And some munchies :)
And if I do end up being in for longer then oh can bring in extras.
I think as long as you have enough for one night then that's enough if you have people to help bring in stuff.
Or if your worried about bringing in loads of stuff then keep extras in the car (if it's being left up the hospital).
