Food and drink. I was soooo thirsty after each birth (I have three kids). Personally I wanted Lemonade and ribena. And loads of snacks. Nice ones. Not healthy ones. Though I made dh bring a lovely M&S fruit salad each day too (in for five nights with dc1).
Pen and paper. If there are medical things you will want to write down explanations and questions as you won’t remember them.
Phone charger.
Magazines. Something v easy to read while waiting around
Headphone. To listen to podcasts etc especially if a long boring induction as I had with dc3
Money including vending machine change
A pillow. Hospital ones are awful
I struggled to feed all three of mine and took a bottle and formula in for numbers 2 and 3. They advise against it as they say this stops you trying hard enough to bf but I found the safety net v important. They do great little packs of pre sterilised bottles for newborns which are perfect
Your own supply of drugs for after. Though this will be frowned upon as they keep records of your drugs etc. But who wants to wait for paracetamol when having after pains when you could bring in your own stronger stuff.
An actual list of phone numbers somif anything happens to your phone you can borrow someone else’s.
