Be mentally prepared for some insensitive idiot childless friend to ask 'why have you still got a bump?'
Know that everyone will have an opinion but only you are the parents and what's right for you is what's right for you.
I saw The Baby Whisperer on TV years ago and she did seem helpful and confidence-building -much more than that Gina Ford woman who timetables when you are allowed to eat your own breakfast! (although my cousin and SIL both felt secure in slavish adherence to GF's insane routines so if GF works for you, go for it). Whatever makes you feel confident.
Breast-feeding is a bit tricky at first, and not all babies are instantly good at it, but it is worth persevering with. In the early days your boobs can be as taut and large as a football so the baby sort of bounces off. In this case try expressing a bit of milk out first. The nipple has to go a lot further into the baby's mouth than I realised for them to be able to create suction. They need to have a really wide open mouth for it to work. Don't worry if your baby's lip gets a blister on it from feeding - this doesn't bother them. For sore nipples, try Lansinoh (it is also the best lip balm money can buy)
Breast-feeding can trigger an instantaneous desperate thirst so get a pint of water before you start. Or shout for one!
Until I had DD1 I had no idea I would bleed for so long after the birth.
Teeny tiny babies can be a bit dazed for a day or two and might just sleep and sleep. Don't panic. You will look back on this time in awe.
When they do wake up, they can give you such intense, deep stares it becomes almost unsettling, like they are actually not babies but very old people.
Breast-fed babies don't do much poo. Mine certainly puked a lot though.
