I broke it down into:
Sleep- Somewhere to sleep - recommend a next to me type cot, cot sheets, Cellular blankets. My girls love white noise but i tested it out using you tube video with them before buying a specific white noise toy/machine.
Eat - bibs, bottles & steriliser - recommend cold water steriliser.
I wouldn't recommend getting a breast pump until baby is here (you can easily get on amazon prime if you feel its necessary) but if for any reason you dont take to breastfeeding then it would be a waste. Same goes for loads of breast pads. I never produced milk so ended up giving away pump, pads and lanisoh cream (expensive!).
Transport - car seat & pram - go and test out prams when you can as some are really heavy, some are all terrain etc. Depends what you want to use it for.
Cleaning - change bag, change mat, muslins (lots!), nappies, cotton wool & sudocrem/bepanthen (metanium is amazing but too strong for newborn bum). Baby bath/bath seat, sponges.
Clothes - some vests, sleepsuits and cardigans if winter baby & hat. I had so much given to me though that i didnt buy any clothes until they were in 3-6 months.
Medical - thermometer, saline nasal spray, calpol (need for jabs), nasal aspirator
Play - playmat, soft books, rattle etc.
I wouldnt bother with a baby monitor until they are at least 4-6months old.
