Ooh, exciting times and congratulations in advance on your pending new arrival. Much has already been said, but here's my tuppence-worth too:
I bf-ed all the time. All the time for weeks and weeks.
I was very tearful for weeks too. Keep an eye on this however, as although I was ok by 10 weeks, I was a bit low for a while (turned out, my LO had severe reflux, so our first three months were a challenge at times).
Don't let if possible others hog the baby/hold him/her/generally fuss too much for too long when still tiny. It's so much for them to cop with and they can get so overwhelmed. We still have this issue with PIL 7 months in and it's a nightmare at times, as he never gets any peace when they're about.
Take LO into the bathroom in a buzzy chair. Mine loved the noise of the shower, the warmth and the general ambience. And it meant I could wash...
Look after your boobs. Pop on Lansinoh nipple cream all the time, as it really makes a difference. It's a wierd yet amazing feeling when your milk arrives around day 3! I was so excited and woke up DH to show him my wet vest top :) Kellymom website is very good.
Everyone will tell you to sleep with LO does. I never really managed this, but rest if you can sometimes.
You can express milk from v early on, and it can help if you'd like LO to take a bottle later on. We didn't have any nipple confusion (Mam bottles are very good). But this is a matter of personal taste and one for you to decide as and when.
We didn't bath our baby that much at all for first two months. In the first few weeks, it was maybe once a week, with a swab over each day with a clean warm flannel. once he was about 7 or 8 weeks, we upped baths and by 3 months, every night.
Don't let HVs or GPs bully you. I was asked in mid Feb when LO had his first bad cold and cough if I was a first time mother which bugged me. It turned out to be a chest infection that needed antibiotics, so even if I had 12 children, I'd still have called in. Ring them as often as you need to to get your baby looked at. You'll know instinctively if something's not right. We were in the surgery a lot when he was tiny due to reflux as he was miserable for weeks and weeks.
Sorry, this is very long!
Lots of luck with everything, you'll be great :)
