I would get a carseat so you can get the baby home. And a moses basket for the baby to sleep in. Nappies and baby gros and vests, cotton wool to change nappies. If you live near shops, you can just send people to get stuff for you. even a buggy - you can just go to mothercare and pick them straight up.
Somewhere for the baby to sleep 4 fitted sheets for whatever it sleeps in a couple of blankets
A car seat if you need one
Some method of transporting the baby - a sling or a pram
A few all in ones with feet (say 6) 6 vests with poppers between the legs a jumper or cardigan a hat
Bottles, formula and steriliser if you don't plan to breastfeed
nappies cotton wool olive oil for baby's skin
Best of luck. I know the feeling of not wanting to jinx things, but you don't need masses of stuff for a new baby. The above are the things I would ideally want to have on day one, but in truth babies only really need to be warm, fed and to have cuddles.
Sorry for your losses, I hope and pray that this time things will go well for you.
If you really want bare minimum, then you do not have to get the moses basket or anything for the baby to sleep in until you come out of hospital.
For hospital you will need minimum: 3 babygros, 3 vests, and a hat, one packet of 1st size nappies, and some cotton wool. You will need blankets for the baby to be brought home in, plus possibly a baby cardigan.
You will need the car seat sorted to ensure that it fits your car, unless you are travelling on public transport.
Any more that is needed in terms of clothes or other baby essentials can be bought in by whoever is visiting you afterwards. All other things like any bottles or buggy/pram as other here have said, could be left until you are back home.
Kamilosan nipple cream is very good (baby can breastfeed after you've applied it), I found it to be a lifesaver. I got my nursing bras from M&S, I still wear them at night (it is 2 years since I breastfed!), just to give some support. They are very comfy. I think they come in packs of 2.
You will get some bits in your Bounty pack, like nappy cream etc. You can get moses basket sheets (Mothercare/Kiddicare?), or if you are handy you could adapt some normal sheets.
Take care and I wish you all the very best, am looking forward to seeing you on here later on asking advce on newborns
Bravado bras - I wouldn't wear anything else make a huge difference compared to the bras on the high street. They come in S, M, M+ sizes so that they can last you during pregnancy, post birth and beyond. This time I've just bought some new Bravado bras while pregnant knowing I can continue using them for breastfeeding. I did BF my DD for nearly 2 years and the Bravado bras had fallen apart by then. I would buy at least 3 bras.
I would buy a breastpump - I never expressed milk for DD to drink but very handy when engorged, when baby decides to sleep more but your boobs don't realise!
