Hi Katherine,
I've had two completely different experiences of BF-ing. I'd like to share some of my - very personal - experience in the hope that it might help you. I'm braced for a flaming but I'm going to tell you how I found it.
Baby 1 - I have always had high expectations of myself, bit of a perfectionist and a control freak if I am honest. I read all the books, went to the antenatal classes, was committed to BFing and then DD arrived... she spent 12 hours a day on the boob and the weight was still falling off her. I sobbed and sobbed when the HV told us to top up on formula somewhere around day 10. I expressed for 3 months as she never got the hang of BFing, for reasons which I'm still unclear about. So, based on baby 1, my advice would be:
a) get to a breastfeeding support group BEFORE baby arrives - have a good look at someone who is BFing and learn what effective feeding looks like. Get to know what to look for with the big gulps so that you can tell if they are properly feeding and swallowing or just comforting/flutter-sucking.
b) If you have a hospital birth, make 100% sure you are happy with how feeding is going before they discharge you. Do not be afraid, as I was, of making a fuss and asking midwives to observe you feeding.
c) If, for whatever reason, BFing doesn't work out, it is not the end of the world, it does not define you as a mother, and if you give it your best shot and it doesn't work out then do not beat yourself up over it. Sometimes other considerations should be taken into account and prioritised over BFing. (Flame me if you like, but I am thinking of things like the mother's mental health, the relationship with your baby - I am talking from my personal experience here and a hellish first 6 months which was primarily centred on the feeding issues.)
d) There are more things that can cause problems with BF than the "oh, you might get sore nipples, and watch out for mastitis" that my antenatal group flagged up. I don't mean to scare you, but just to make you aware that problems are fairly common - if you don't have problems, then that's great but if you do, you're not alone. Of my friends who BFed, tongue-tie, oversupply and nipples too large for baby's mouth were all issues that were overcome successfully, but certainly my antenatal class made it seem that the only problem anyone ever had was latch-related. And it aint always so. BFing may be natural but it is a learned process for both you and baby, and there may be hiccups along the way. Personally I think had I known that in advance I would have been better prepared and felt less of a failure and less isolated.
e) If you do have problems feeding, and I really really hope you don't and your baby is more like my DC2 on that front - if it's a Sunday and the midwife is likely to tell you that you need to start topping baby up with formula urgently to rehydrate them, make sure you know a shop that has late opening so your DH isn't driving round the city trying to find somewhere that sells it past 4pm. (Or buy a carton or two in as emergency supplies - although I know that will be controversial as people will say it puts temptation in your way. I am only speaking from my experience though, and it was pretty obvious, had I been in a less-hormonal and sleep deprived state, that something was going to have to be done at that point as the BFing wasn't working out.)
On the positive side, Baby 2 was completely different - he wasn't that interested in latching on when he was born, took about an hour to get him on properly but this time I knew what I was looking for, I had it in my birth plan that I wanted to feed asap after birth and that it should be properly observed, and apart from a really painful let-down reflex for the first six weeks, he's basically been a dream as far as BFing goes. Whack him on anywhere now, totally laid back about sticking him on the boob out and about - the Vertbaudet tops are my favourite for discretion - so top tips based on my experience with him:
a) Get it written into your birth plan that you want to feed asap after birth. Make sure it is observed (yes, I know I keep banging on about that.)
b) Be prepared for cluster feeding to take over your evenings/days at various stages. Just because he came off the boob half an hour ago doesn't mean he can't want more. :) Invest in good books, DVD box-sets, and get comfy on the sofa.
c) BFing does get easier: I remember thinking I would aim for 12 weeks to start with, and at 6 weeks it seemed impossible, but taking it one feed at a time it did get so much more comfortable and convenient - now at 6 months and it is a breeze. Whack him on, off he goes. Feed are really quick these days, much quicker than bottle-feeds and less faff as it is 'on tap'.
d) And bracing for another flaming... If you want baby to ever take a bottle (expressed breastmilk or whatever) - in my experience, and what my HV advised, you need to get baby to take a bottle around the 3 week mark. In my experience (and anecdotes aren't data, I know) if you leave it til 6 weeks when some people recommend to introduce a bottle, you've left it too late. DS got used to the occasional bottle around 3 weeks and I have had no nipple confusion at all with him. I have several friends who waited til around the 6 week mark and their babies refused to take a bottle, some only grudgingly took a cup. But do your own research and make your own mind up on that one.
e) Never make decisions about giving up BFing in the middle of the night. Things always seem worse then, and you won't be thinking as clearly as you will in the day.
I do think every baby is different, and even with the same mum you can have different BFing experiences depending on the baby. I had a bit more of a clue second time around though and I am sure that helped. I'm going to post this and run as I know some of the points I have raised will be a bit controversial, and some of the people on these boards scare me. :) But I hope it helps you, and wish you all the very best for a straightforward birth and BFing experience. And sorry this is so long!
