I don't think I could be with a man who felt entitled on voicing his "preferences" on how I gave birth, or how I decided to feed the child.
I heard someone's husband make a pretty derisive remark about his wife getting an epidural once, and I had to physically leave the room to prevent myself from kicking him repeatedly in the nuts whilst shouting "WHAT'S THAT? YOU WANT THE PAIN TO STOP? YOU'VE GOT HOURS LEFT SWEETHEART. NEXT UP IS A MELON UP YOUR ARSE".
To be fair, he was a total knob end.
Whilst of course he is entitled to say "I would really prefer for the child to have breast milk" that's as far as he can push it. The only justification you should ever have to give is "I don't want to do that". He isn't the one who will have to deal with cracked, bleeding nipples.
Of course you could always " just try it out" but you aren't OBLIGED to. It's really no-one's business - you have to make the decision which will have the greatest positive impact on you.
Lots of women in my family haven't been able to breast feed (they didn't even have milk come in), and had to rely on formula. I hope it isn't genetic, as I would like to at least see what it's like before making a decision, but I wouldn't judge someone moving directly to formula.
It's absolutely horrific to imagine someone doing something as invasive, difficult, and (potentially) painful as breast feeding through obligation or pressure. I honestly think that would test my sanity.
(to note: if you like breastfeeding, or found it easy, then obviously none of the descriptors above will apply to you. But if you don't want to do it, or really struggle with it, then having a baby hanging onto your body on demand is seriously invasive. It's just a question of your views on it, which are very difficult to change)
