Yes on the BF thing - find out where your nearest BF cafe is before your have baby and if you on ML already then pop in. they will love to meet you and your bump and it will mean that you have gone there when feeling like a confident you, rather than "I can't believe this is happening to me - am I really a mum" and much more tired version of yourself. Of course if you don't get the chance - still pop along even if you are not having any probs. It is a lovely place to meet mums.
I agree that if you can read or speak to someone who has or is BF about how to hold baby/latch etc in advance it will give you a bit of a head start (but of course a bit like reading how to ride a bike/having sex! You'll never know how it feels until you do it).
And yes it will take up most of your time, newborns need to feed 12 times a day (yup, thats every 2 hours) so if you have a sleepy baby then you will have to wake them up (only in the first few days, especially if they knackered from a full on labour!). Your boobs will probably tell you but in a sleep deprived state you may loose track of what boob you fed with and when you started/finished the last feed so it can be handy to keep a not to start with (as with everything - try not to fret about it)
Additionally (Sorry I am a BF peer support so am a bit obsessed!) you NEED to take it easy for successful BF. If you get run down you are more likely to experience problems (such as blocked milk ducts and Mastitis) but the risk of these can be reduced it you don't run around like a blue arsed fly. Relax, relax, relax. Sleep, eat, drink. Don't ever keep pushing yourself to try and do everything or you'll be knackered, grumpy and your tits will hurt!
You'll be excited (and might have a rush of adrenaline) to show your creation off to EVERYONE! but take a bloody chill pill if this happens! Limit yourself and don't go crazy socialising. Might be good to forewarn some friends and family of this in advance?
And if BF doesn't work out (it can happen to mums who have BF 2 or 3 kids and then number 4 just doesn't work for them, so don't take it personally!) It's just life. Move on, feed your baby food. In a couple of years (like another wise mumsnetter advised) "one day he'll eat cake!" and I'd like to add, chips, crisps AND fruit shoots (absolutely foul). Cow & Gate positively juice of the gods compared to all that shit!
