I think breastfeeding is different because… public health people decided it should be, and we’ve internalized their messaging.
I haven’t gone around and checked much, but my gut impression isn’t that this is about public health people. I think it’s more like a Chesterton’s Fence backlash against previous generations’ experts claiming that formula was obviously better. IIRC, mothers were warned against using breastmilk and told to go to formula instead, because it’s Scientific™. So it took some cultural pushback to reclaim evolution’s solution to feeding newborns.

My impression was that the backlash you’re describing is causally downstream of efforts by public health people to promote breastfeeding (and pro-breastfeeding messages in hospitals, etc.) Certainly the correlation is there (https://www.researchgate.net/publication/14117103_The_Resurgence_of_Breastfeeding_in_the_United_States) but I guess it’s pretty hard to prove a strict cause.
