JLo didn't say she chose not to breastfeed because of the challenges of breastfeeding twins.
She said she chose not to breastfeed them because she believed that bottlefeeding is best for them. That's what her words in the interview suggested. So no - it doesn't sound like she made an informed choice.
Nobody has insinuated that feeding twins is easy. Most mums of singletons get duff support and no help around the house to enable them to establish breastfeeding, let alone mums of twins who face even more ignorance.
But it's probably a damn site easier feeding one set of twins with a staff of 30 to take over every single other responsibility you have including cooking, cleaning, looking after other children, dressing yourself, doing your own hair, changing and settling your babies, answering your phones, paying your bills, greeting your guests etc etc, than breastfeeding one baby while caring for an older child, a toddler, a dog, a house, doing the school run, working, cooking, shopping and studying, which many of us on this board have done.
"And feeding your children food is a far lengthier and imho more imortant process than the brief 6 months or so that babies are breastfed." Well - that's your opinion. I'm of the opinion that infant feeding in the first year of life has repercussions that last a lifetime and the research backs me up on that.
In any case - no I wouldn't be depressed at mothers choosing not to give their children organic food. But if a super rich pop-star deliberately decided to feed her children on a diet that - like formula - would raise their blood pressure, make them more likely to develop diabetes, and more than triple their chances of needing hospitalisation over the following year of their life, on the pretext that it was 'best for them' then - sorry - it would raise a lot of questions in my mind about what sort of information she'd been given about her feeding choices.
