I'm 3 weeks post partum, so I'll just tell you what I actually used. For my son all I brought was a blanket and outfit for him to go home in, along with the car seat. For me I stayed in the hospital gown the whole time (I had a C section) and brought a robe from home to cover the back when I walked the halls. I brought travel size shower stuff along with my toothbrush and tooth paste. Also a brush or make up if you feel like getting ready. Also clothes to leave the hospital in. I used the hospitals big pads because I was bleeding alot, so it was much easier. Also, contacts or glasses.
For your baby make sure you have a pack of nappies and some cotton wool balls for cleaning/washing etc... about 3 vests and 3 all in ones... hats a mits and a coming home outfit.
For you make sure you have some comfy clothes and slippers as well. X
Almost everything you need is provided for your baby in the hospital. All you need are a couple of outfits for baby and yourself. An extra blanket, hat, socks if you choose and your car seat. The less you have to keep up with, the better.
