I think that it's very easy to become defensive no matter what side you bat for. Does that make sense? My dd (8mo) was bf for 6 weeks. I hated doing it and felt pressurised into doing it. Which meant that when I stared bottle feeding I now know that I did become defensive in my decision to switch. I knew from the beginning that I didn't want to bf, but found the pressure to do so from doctors, mw, hospital staff etc very overwhelming. As a new mum I felt like I just nodded along for an easier time. It made the first 6 weeks of dd's life quite a difficult time for me.
Switching to formula was the best choice I ever made. It meant that as a single mum the pressure was taken off of me to be the only one that could feed my daughter. She started to sleep through the night instantly. She was no longer crying after a feed, and was far more settled. I honestly believe that my daughter was permanantly hungry for her first 6 weeks of her life as she was definitley not getting enough food from me and was always unsettled.
I'm pro breastfeeding and think it's great that some mums want to do it, but from my experience found that medical staff really made you feel like crap for even considering to ff. And as a first time mum, I was certainly backed into a corner as I didn't have the voice to put my foot down. If I ever had another child, I know I would do and say what I wanted and what I felt was right for my child. Though I'm pro bf, I'm also pro ff. It's a womans choice to do what she wants imo, if you want to ff - fine, no questions asked. This is how it should be, ime, it's not.
Bf made me very uncomfortable. I wouldn't go out if I knew my daughter would need a feed as I hated the idea of getting my boobs out to feed her in public. I'm not even really a shy person either, I'll quite happily sunbathe topless on holiday Seeing women bf can make a lot of people feel uncomfortable though, especially those of an older generation. And I think that that can be forgotten sometimes.
I'll also add that I suffer from pnd. Have done from day 1, only started getting help for it a month ago. The way I felt about bf and some of the difficulties I had with doing it, are definite factors to my pnd imo. Was made to feel like s**t when I stopped bf, the pressure to do it in the first place, the pain it caused, bleading, cracked nipples, unsettled, crying baby for 6 weeks, feeling like a terrible mum because I couldn't settle my own baby because she was hungry etc. All factors to the crap way I felt/feel now.
For mums who want to ff, do it. If that's what you're comfortable with doing, go ahead. Same applies to mums who want to bf. I think there needs to be far more support for mums who ff instead of the bog standard 'well breastfeeding is what's best for them you know.......'
