My essentials list for baby-
somewhere for baby to sleep, both downstairs and upstairs. We went for a moses basket and a next to you crib. Sheets to fit on both, at least 2 for each. Cellular blankets, a couple for each place in the right size. I got all sheets and blankets from Asda I think. I used a baby sleeping bag, but not until a couple of weeks in, I think babies might be too small til then.
Something to cart him/ her around in. We chose a pram, needs to lay flat at first. Others go for a sling, or both. A blanket for the pram. A bag big enough to fit the million different things in.
A car seat, stage 0.
Nappies, wipes, cotton wool, sudocrem.
Bodysuits and babygrows, I would start with at least 12 of each, as they can easy go through a few a day and you don't want to be worrying about running out on day 3 and trying to wash and dry them. Socks, mittens if they're not on the sleepsuits, a hat or two, at least a couple of cardigans.
Feeding- breast feeding aside, we bought a couple of packs of tiny pre-prepared formula in a bottle to take to the hospital just in case. They're available at Asda. Brand, just pick something common- cow and gate, SMA are both found in loads of places.
I bought a perfect prep machine and bottles, but I was quite clear that even if I breast fed I would mix feed, so happy to prepare for that.
A baby bath/ seat, some towels, some kind of top to toe wash and flannel/ sponges.
Have fun! This is a lovely (but expensive!) bit.
