Good luck. I am sure there are good bit and bad bits involved with FF and BF, and I am NOT about to join that debate.
You asked for my experience - here it is.
I bf my 2 DS, and found it pretty easy. Sure it was a bit painful for a couple of weeks while my nips got used to it.. But it was worth it knowing I was doing the best for the baby. The pain very soon stopped, but of course it came back again when teeth grew. I yelled at them and put on a cross face, and the biting soon stopped. I didn't have constant screaming or attachment. You don;t need to worry about how much they are getting so long as they are growing well and are weeing and pooing. It is SO easy not to have to figure out bottles etc when you are going out, and to be able to respond quickly if the baby is hungry. I personally could not have done with having to faff about with a bottle when there is a hungry baby to be fed..
I did get mastitis a few times at the start, but Dr gave me anti-bs and it went away very quickly each time.
Be determined to do it, that's my tip. I had decided to do it and I stuck to my guns. Luckily I had a very good local cottage hospital with a 4 bed maternity unit, which only had me in it, the days I was in with DS1, so had two midwives all to myself who were FAB with helping me get started feeding. There was also a great bf counsellor who was at all the baby weighing sessions to help everyone. She helped with the latch a few times at the start. Sometimes when they were having a growth spurt my milk didn;t seem to be enough, and they wanted feeding more often, I was tempted to try to go onto bottles, but I just fed more and the milk soon increased again. They woudn't take a bottle anyway. Have you tasted formula? barf! I didn't blame them.
I was told to drink LOTS and LOTs of water and eat a broad diet including plenty of protein. An extra cup of water a day was NOT enough I needed pints extra, and ate loads of things like shepherds pie, spag bog etc. I had LOADS of milk..but I didn't lose any weight!!!
eerr what else? It's FREEEE!!!!!
I NEVER had an issue with feeding the baby away from home. Never got a single comment or look. It was perfectly possible to feed very discretely by lifting my top UP rather than pulling it down.
With DS1, I went back to work at 6 months too, but I did manage to express quite a bit of milk for three months at work. Twice a day to start with, and then down to once. I used to have to dash to the medical room ( big comany) to express if a meeting went on a bit long as I felt I was about to explode. We had a freezer I could store the milk in till home time. However my Mum who was looking after him for me said he only took a bit of milk from a sippy cup anyway - most of my milk got thrown away. But he was on solids by then anyway so the milk was not so desperately important. Anyway he carried on growing like weeds and took water from a sippy cup, so it was fine. I carried on bf at night and before and after work till they were a year (plus) old.
DS1 weaned very easily at 1 year old. Literally something like 5 seconds of crying. He was only feeding at waking up time then, so we just distracted him with breakfast and he was fine. DS2 was a bit more determined. I only managed to stop at 18 mnths with him and there were a few more tears. I had really had enough by then though.
Give it a good go - what have you got to lose?
