First time mum question alert - what does baby sleep in?

[pinkie87]

Help! Are you meant to swaddle them for a few weeks? Or is that a no no? And then do you use blankets or sleeping bags? The whole bedding thing seems like a bloody minefield if you are a first timer! Just trying to get on top of what I need to be buying.

Thanks everyone (carks thanks for a great explanation). I'm obviously quite early on in my pregnancy so haven't done any classes or anything yet but the first time mums session with the health visitor sounds helpful. :) so much to learn!
