I had a pretty straight forward delivery, here's what I used.
After the birth I had a few stitches then I went for a shower to get cleaned up so needed toiletries, pads (take a whole pack and the super thick absorbent ones) and a change of pjs.
Then up to the ward with DD, we needed to stay overnight as I'd had GD and they needed 3 sugar tests for DD.
Was starving and had missed all meals, so raided my snack bag. I'd also taken a bottle of squash to turn the lukewarm jug of water into something bearable,
Lots of being awake overnight. It was hard to sleep in a noisy well lit room and I just wanted to watch DD anyway. So I ate a lot of snacks at weird times. Needed charger for phone.
In the morning needed a change of clothes and toiletries for going home in.
If they offer you a pain killer suppository take it, hell ask for it, it's some kind of super ibuprofen anti-inflammatory and basically numbs your bits for 24 hrs. It's fabulous!
Be sensible with what you pack, there's very little space for stuff near your bed and I was basically just left to it, so had to manoeuvre baby and if you're trying to shift a baby from crib with bags everywhere, no space, no help and a sore tired body it gets complicated.
Breakfast was basically being pointed to a room at the end of the ward and told there's a toaster and stuff in the fridge, we all had to make our own while holding our newborns and waddling in pain.
