Okay, so yes Mexico is very poor, but mothers choosing not to breast-feed should not be called out as an example of what not to do.
Don't get me wrong. I'm not against breast-feeding, nor am I advocating formula feeding. What I am trying to say is that women should have the option to choose what's best for their lifestyle without being judged or made to feel guilty about their decision.
When I had my daughter, I already had in mind that I was going to formula for various reasons -- I had read up on formula, I intended on going back to work because I had to, plus I wasn't breast-fed and neither have many other people I know and we were no different than those we knew who were breast-fed.
