Bottles - If your BF'ing I would personally go for the tommee tippee closer to nature. They are far better IMO being extra wide neck for combining breast and bottle. Get one or 2 to start and you can cold water sterilise.
muslins - I hate muslins and find they are overpriced. Cheap hand towels from tesco did the same job for me for less money. I may be alone on that opinion though.
baby bouncer - Yes I loved mine. If you have a clingy baby though you are better of with a sling. I borrowed mine from a friend so didn't invest any money. DS1 was clingy and I didn't use it very often. Nice to have somewhere safe to put him though. DS2 loved it.
moses basket - Probably not essential but nice to have or a crib if you can afford it. Again I was given mine.
cot - Yes!
pram - Yes!
changing matt - Not essential but again nice to have. I mainly used a towel with DS2 and am not buying one for DC3
nappy bin - As PP said unless you live in a flat not really nec.
baby monitor - I would get a cheap one that allows you to hear the baby. Don't see that is nec to be able to see or talk to the baby but just my opinion.
bibs - I have never really used them but my mum and granny thought them essential. Don't buy too many to start with, maybe 5 to see if they get used. Ones with a waterproof back stop milk/sick soaking through on to clothes but make sure the fronts are absorbent otherwise everything runs off!
Car seat - Yes
Sleeping bags/swaddle blankets are not essential really. A standard blanket can be used for swaddling. My SIL swaddled my DS1 in a pillow case once!
Lansinoh - I have never used nipple cream of any kind. Wait and see if you need it before buying. It is not cheap!
I bathed DS2 in a sink for first few weeks but I would recommend a bath support for time between when they are too big for sink but too small to sit up in bath.
Can't think of anything else to get.
