When I was pg my DH asked me if I would b/feed. I had never even thought about it tbh, and had just thought bottles. I said I'd try but not continue if it wasn't working due to the amount of negatitive that people spoke about (family)
Anyway, the first few weeks were bad. We just couldnt get the hang of it in the first few nights. I'd had a section so moving was difficult anyway, and I think without a very supporting midwife at the hospital, I'd probably have packed it in. I think when I left the hospital some of the midwives assumed I'd give up (we were critised for giving her expressed b/milk rather than "forcing" her to b/feed or take formula) and one nasty midwife had me crying when I asked for help. Once we were home, we seemed to settle into a routine and eventually it became second nature.
I am still b/feeding, shes nearly 16 months, she has "growing up" milk at the CM (up until a year I expressed at work for her to have in the day) and she has b/feed in morning and evening.
People at work often ask me about b/feeding as they know I have/am doing it. I never tell them that it's a better way. I never tell them that formula will harm their child. Because I appreciate that it is the last thing that somebody wants to hear.
I just explain how I found it, how it can get easier, but not to feel as if its a failure if it is not sucessful long term, but a sucess for the times you did.
A friend of mine is on mat leave with her second, we had our first at the same time. She didn't manage to sustain b/feeding the first time, and when pg the second time she explained her issues with the non b/feeding the first time, and she felt like she'd been pressured into giving in. But even in that situation, I tried to tread carefully because its easy for people feelings to be hurt when it comes to their children, as we all want to give the best but there is no rule as to what is best for everybody, just best for that mother-child combination.
My DH is far more vocal in being judgemental. He is very supportive about b/feeding but he doesn't judge about that, he is very vocal about dummies though, and I have had to kick him several times in the past!
