Both my kids have been on formula since my wife can't breastfeed and they are super healthy. The kids that I know that have been breastfed have been to the hospital several times while we haven't been there at all. I don't argue with science but breastfeeding have been blown way out of propotion. It's ok to use formula, the kids won't die or get permanent damages.   
  
What you should care about is the mental health of the parents. Breastfeeding and not getting any sleep will make some moms snap and when they do, they might hurt the baby. The reason we teach something obvious as not shaking the baby is because not getting any sleep or rest while a baby scream non stop will you make you crazy.  
  
Edit: This just isn't my opinion. We have talked to nursers and doctors about this. The positive effect of breastfeeding is very small.
