My situation is a bit like Kage76.
I wish that I could BF. I went all through pregnancy expecting that I would be able to and that there would be no difficulties with it. I stupidly went in with the opinion that as I have boobs I'd be able to BF !
Anyway Isabella lost too much weight at first. I was BFing at every opportunity and this soon led to her feeding from 10.00am until 11.00pm- constantly, we're literally talking 20 minutes one side, swap, 20 minutes the other side, swap, 20 minutes one side, swap...(you get the idea) She was latching on fine, I'd had it checked by about 5-6 people. We started topping up so that she would actually go to sleep, as she wasn't sleeping during the day at all. By 5 weeks old she had not yet got back to her birth weight.
I remember meeting up with a friend, her LB is two days younger than Izzy...he looked great, chunky, healthy. He would have 20 minutes each side and then sleep for two hours. Izzy looked pale, had shadows under her eyes and she looked skinny and ill. That was enough for me, after going home I cried for hours as I went on to a forum and spoke to some other people about how they feel about FF.
One person on there basically said that it wasn't working, Izzy was not feeding well, she was constantly crying and that it might be worth trying 2 feeds of formula and see how it went.
Izzy wasn't sleeping during the day while BFing, after that first bottle of formula she slept for three hours.
Then had another feed and smiled. She smiled a real smile for the first time, now I know that this may have happened while I was BFing but in reality she was never off of my boobs so it seems unlikely!!!
I felt horribly guilty at first like I was failing, but I'm fine about it now. At the end of the day I tried, I tried really hard but I think that there was an issue with my supply, I never had hard boobs a few days after birth, no leaking, if I gave her formula instead of BFing I didn't get sore boobs, I could go 6-8 hours without BFing her and still not be leaking or be sore. Iz is now healthy, she sleeps during the day, sleeps brilliantly at night and more importantly I don't resent her for being hungry, if she wants to be on me all day now it's not attached to my boobs but looking at me, smiling at me and listening to me singing or talking to her.
I will try BFing the next baby we have but I will know that it doesn't matter if I need to switch to FFing again because I will be able to look at my daughter and see a healthy baby.
