I think a lot of peds are just trying to not stress out moms who are, for whatever reason, formula feeding. They know the benefits of breastmilk, but they also know that formula feeding is not the end of the world, and so they don't want to lay a guilt trip on the moms.
My experience with my pediatrician led me to think this. My son had to get supplements of formula in the first two months because of my low milk supply. My supply gradually increased, and today at 7 months he gets all breastmilk. In those early days, I talked to the pediatrician in tears about my son getting some formula. She told me it was fine to feed formula, if my supply didn't increase it was perfectly ok, my son would still be healthy. But now that he gets exclusively breastmilk, my pediatrician is all about telling me about all the benefits my son is getting from that milk. So I think it's more that a lot of peds have seen stressed out moms who wanted to BF and struggled, and they don't want to add to the stress on those moms. I think that most of them DO know the benefits!
