Remove nail varnish, both nails and toes.
Things to pass the time/entertain. I assume you are having an elcs, you may have to go in very early, but you may not be first on the list, you could get bumped for emergency procedures.
Certainly take snacks/drinks, most hospitals will have a patient kitchen, with a fridge/freezer, microwave, toaster etc, you can leave things in the fridge, sandwiches, fruit or even ice cream/ice cubes for drinks. The ward I worked in always had a stash of salads/sandwiches/yoghurt's for ladies that had missed meals, but you can't count on it.
Pillows very useful, they are usually in short supply on post natal wards.
Mp3 player essential, I would use this to block out noise rather than earplugs, more likely to hear your baby. Post natal wards are hellishly noisy unless you have the good fortune to be put in a side room.
I would 100% read up on breastfeeding, watch latching videos on youtube or wherever. The advice given in hospitals can be abysmal. The breastfeeding advisor I had with ds2 was useless (I actually used to work with her on the ward), she half heartedly tried to latch him on, then wandered off saying he wasn't hungry
, the other bfa was a mentalist and was really quite rough with the babies. Bf is the same whether cs or vb.
Money for the TV thingy (if you don't have a 3g ipad, or laptop with dongle
)
Good luck and congratulations.
