I didnt use muslin really for DS. He wasn't sicky and just used bibs. But I've got some in for DC2 just in case this one needs them.
You hardly need any of the stuff all the books/websites tell you, and even once the baby comes you can go out to the shops and buy any bits you didn't think you needed but turns out you do.
Unless you want your washing machine on constantly, you need a fair amount of vests, sleepsuits, scratch mittens, bibs. A few 'proper' outfits for daytime is always nice, but plenty of people use sleepsuits as clothes for a newborn.
Trying to work out your dates - mid-nov baby? You will want a snowsuit for going out. And hats. I found a travel system better value than a car seat and pram. You will have to get them both either way. A cosy toes and rain cover is good for winter months.
Nappies, wipes, baby wash and a teeny tiny sponge, a moses basket or crib, 2 sleeping bags for snuggly-ness, 3 sets of bedding. If you've got a sink, you dont need a baby bath. I found the top n tail bowl useless too, and the changing mat, and the masses of nappy creams and baby soaps and the baby manicure/comb/brush set.
I found the baby sling and bouncy chair invaluable. I also loved popping DS on the playmat and watching him gazing at the little animals. He also had this little aquarium thing that made water noises, lit up and had plastic fishys that swam about which he loved. I spent about £60 on a mobile which he wasnt fussed by and this piano thing for him to kick in his cot, which seemed to irritate him.
If you're bottle feeding, you need about 6-8 teeny bottles, a bottle brush, a steriliser, formula. I never saw the point of bottle warmers because the water was already hot? But maybe there is and I just never found a use for it! Going out, you might like to get a powder dispenser thingy, to make up bottles on the move.
