My hospital suggested to bring the following: (they only provide nappies for while baby is in hossy)
- 6 grow suits
- 6 singlets
- 6 bunny rugs
- 2 bonnets, mittens, bootees

I've washed and packed all the above in 0000s and have got washed 000 at home if need be. Because the Bonds wondersuits have the feet enclosed and also have the ability to do that with hands, I guess the mittens and bootees may not be necessary, but I have packed 2 or 3 hats if I need them. HTH!
