Yep. Around the 70's or 80's, there was a reversal of the consensus of whether formula is just a good as breastfeeding. Personally, I think even pumped breastmilk isn't as good either because it lacks the psychological effect of skin-to-skin contact, the exchange of smells, and the immediacy of breastfeeding. I can't imagine leaving a 1-3 month old screaming every time its hungry while the parent spends 10 minutes gently thawing some milk. What if he develops some sense that food and security is scarce forever suffers some emotional damage?
