You actually need surprisingly little - if I made a pile of all the stuff I got and never used, and another of the stuff I did, the first would be huge and the second titchy. And I second the advice not to buy newborn sizes unless your baby is teeny.
- Car seat
- Pram or buggy that can recline flat or has a carry cot
- Sleepsuits x 6 (Front fastening: back fastening, and they have to lie on poppers)
- Vests x 6
- A warm cardigan
- scratch mittens (if not integral to sleepsuit)
- Cotton swaddle blanket x 2
- Carrycot on pram, OR Moses basket
- Nappies
- Cotton wool to change the nappy
- Tupperware bowl for warm water to change the nappy (you can't use anything but water on newborn skin for a month - they need to develop the "acid mantle")
- Muslins x 12
- If breastfeeding, Lansinoh cream
A Tummy Tub is nice but not at all essential. I didn't get one - ds bathes with me.
A sling means you can get on with doing things while they snooze happily - unless your baby hates slings, or you hate that particular one. I'd borrow before buying, myself.
Neals Yard bottom barrier cream is the best cure for nappy rash. Treats my eczema brilliantly, too. But you aren't meant to use it for the first month.
If you want disposable nappies, Nature Baby ones cost the same as the premium brands and are a lot gentler on the skin - more breathable and less bleach. He reacts to Pampers etc. with red rash - never has a problem with Nature Baby. Sainsburys, Boots and Waitrose sell them.
I wouldn't buy "outfits" for babies, really, given they sleep most of the time. I wouldn't want to sleep in jeans, and I've had 30 years of practice with clothing; they've been suspended in a fabulous bath all their lives. Even a soft cotton romper must be a shock!
The huuuuge threads on this are in the pregnancy forum, together with most pram recommendations for newborns, I found at the time.
I agree with the "formula in the house" thing. Shops aren't open at 9pm on a Sunday around here, and a dehydrated baby can't wait till Monday morning. Breastfeeding can be amazing, but when it goes completely tits-up an alternative is essential, as I rather horrendously found. My ds only needed formula for a week, but he'd have been in desperate trouble without it. Best thing perhaps is to take a couple of the ready-mixed jars from hospital, and the sterile packed teats, so you have that fallback option without having to fork out for bottles, sterilisers, etc.
Handpumps are apparently not much cop, and no point splashing out on an electrical if breastfeeding goes well.
Congratulations!
