I agree that breast milk is important. But it shouldn't be told that its the only thing. Some mothers have problems producing enough milk. It is wrong to make this mother feel guilty even if she is doing everything right. In my own experience, my son was breast fed for 6 weeks. He was prem and then became very sick. Because of this, I dried up. I was unable to produce any more. The adds on tv that told me that breast was best were awful. I had a sick little boy and the last thing I needed was to be told that I was not doing the best by my baby because I couldn't produce enough milk. I am not alone here. Also, as a side, my sister and I were formula fed babies and we turned out fine! .
I would find that anyone who does that to a woman is a ass. I find it as another form of bullying. This is the society we are creating. Bully people who can breast feed for breastfeeding your child and turn around and bully people who can not breast feed their child because they should be. People are cruel.
Yes, I agree you should encourage this but do it in such a way that those can't, for whatever reason, don't feel like they are less of a mother. I think that is what the original intent was saying, that the way they phrased the adds made it seem like if you don't breast feed you are less of a parent or somehow unworthy of motherhood.
