There is abundant evidence that breastfeeding is best for babies. I profoundly wish that everyone would at least follow the American Academy of Pediatrics recommendation of breast feeding for at least 12 months. From personal experience, I know how little support mothers can receive (and actual DISCOURAGEMENT) especially in the African-American community to nurse their children at all, let only for a full year.
I am a breastfeeding cheerleader: Go Mother's Milk!
However, as a healthcare professional and educator, I have to caution against the dreaded Breastfeeding Nazi. (Yeah, I know some people are offended by the term. No offense intended.)
I have been an educator for many years and a nurse for a few years more. What I have learned from my students is to be a partner to them. Meet them where they are. Hitting people over the head is not a recommended educational technique.
To be professional, we have to remain empathetic and focused but refrain from investing our own emotions into a learning situation. Remain patient and help to remove barriers where you can. Encourage, don't browbeat. Remove your own ego and don't proselytize.
Yes, breast is best and it is a crying shame what we have allowed the formula companies to do to undermine breastfeeding around the world. At the same time, our job is to empower our patients not power over them. We should not sit in judgement of those who choose formula.
