Should there be a warning label on baby formula?

Tweet

I came across an article in the new york times called Breast-Feed or Else that talks about putting a warning label on infant formula stating that not breastfeeding is hazardous to your baby's health. This is a quote from it "Just like it's risky to smoke during pregnancy, It's risky not to breastfeed after" As a mother who exclusively breastfeeds I think that it's a good idea to do this. I think that there is too much pressure to formula feed(in the US anyway)that mothers dismiss the benefits from it. What's your opinion?
