Hi there, I found that I didn't really need anything essentially for the baby, but I did need some things for myself and thought I'd share them with you here - hope you find my 'list' useful!!
Try and get a very squashy sports water bottle - a litre bottle from volvic would be ideal. It's for squirting warm water on your bits, after you've had your baby. Very soothing with warm water and a bit of tea tree oil. You might find it hard to 'go', and the warm water will help with the bruising. After you 'go' you won't want to use loo roll so the water is great. If you've had a cesarean birth, you can put salt and tea tree oil / lavender in it and clean your scar with it. Arnica 200c for bruising and shock is essential and Belles perennis 200c for a cesarean birth recovery. Phosphorous powder 200c to recover from anesthetic and morphine.
Another thing I found an absolute MUST is Soya Leicithin. you can get in a health food shop or chemist - capsules and granules. It emulsifies the fat globules in breast milk and stops you getting mastitis or blocked ducts. Absolutely essential if you're planning on breastfeeding.
Lansinoh lanolin ointment/balm for nipples is also essential. A poppy cushion is great. Also ask them how to breastfeed lying down in the hospital, before you come home. It's essential that you know how to do feed your baby before you come home. if you're going to bottle feed, ask them how much formula etc.
I know there could be a lot of flack for me by saying get some infant formula and a little bottle with infant teat, or a feeding syringe in the cupboard. You might end up mixed feeding, as I did even with the best will in the world to exclusively breastfeed - my midwife advised not to give my DD a bottle before 2 weeks and before 5 - even with expressed milk, to avoid nipple confusion - my DD happily took a bottle of expressed breast milk (some babies don't as the want the boob only). which brings me to breast pumps - if you can hire a hospital grade one for a month at the beginning, to get your supply up.
Get the number of a lactation consultant, before you have your baby. Find if you can a breastfeeding group and go to it before you have your baby. Get some numbers of the other mums there.
Find a cleaner if you can.
Freeze some dinners - more that you think you need - I was in hospital for 10 days and my DH ate all of the ones I had prepared before I even got home with babs... and no.. he didn't cook and freeze some more..
Blackout curtains are a godsend, especially if you have a non-sleeper like I had. Also cotton wool and water is all you need for a tiny newborn's sensitive skin. I didn't put anything on my DD's skin till she was three months (and then it was silcock's base). Get a few packs of baby nappies and then more of the size 1. You'll change your baby about 10 times a day for the first few weeks - it's really unbelievable how many you can go through!! I always used nappy bags and disposed of them in the bin, and didn't have a huge smelly nappy wrapper taking up room.
Try out your baby seats and buggies before yo have your wailing baby in your arms in the hospital carpark!!!!
The book The baby whisperer by traci hogg is a brilliant book. Read it before you have your baby, and get your partner to read it also!! It has a really great section on types of babies, different cries and what they mean, and on routines. Genius.
Hope all this helps, I found that I didn't need any things for my DD, but I needed them for breastfeeding and for my recovery in the first few weeks. I bought the baby equipment after I'd recovered, and after I'd met my baby and knew what would suit us best.
Good luck!!
