The meme in the OP is insensitive and presents overblown "facts" with no sources.
However - breastfeeding is best. Of course it is. Anyone who says it isn't is deluding themselves. Doesn't mean the accompanying guilt is justified however.
IMO we need to look at these things in context. We ALL make decisions time that put our children's safety at risk, for one reason or another.
e.g. not putting children in cars bacause of the risk of car accidents is "best". But, it's majorly inconvenient to live without cars, so most of us do.
Living in the countryside is "best" (34% of DC at my friend's DC's inner city school have asthma), but many (most?) of us chose to live in polluted cities & towns as that's where the work is / our families are.
Breast feeding is best, of course it is. But many women for one reason and another (often woeful lack of support) formula feed.
We need to own our decisions. e.g. I BF my children longer than most on this thread. But I choose to live in a place with high pollution. That's my decision, for better or worse.
Why don't people make me feel guilty about exposing my DC to pollution? Probably because it's not a gendered decision and society loves to make mothers feel guilty.
If people make you feel guilty about FF, tell them to fuck off. You're doing the best for your family I have no doubt.
But, you don't need to pretend FF is the same as BFing, just as you don't pretend living in the countryside is the same as a city.
We simply can't always choose the "best" for our DC - there are too many competing pressures, life's just not like that.
