My older DD's (3.5yrs) first 2 pediatricians (before we switched to a family doc) were affiliated with the umich hospital system.
The first one (birth to 6m) consistently referred to my milk as "high octane" milk and never failed to mention how BIG my daughter was. Because my milk! was so rich! OMG! It *may* have been a compliment but it made me feel like there was something weird about us.
She also started doling out the parenting advice at 2m - including giving us parental "homework" of going on a date - alone - by her 4m appt. It was really pushy and weird.
By our 6m appt, she freaked out that DD nursed every 2hrs or so and a few times at night. And that she slept in our bed. I was told to get her on more solids and that she should be eating 4x during the day and once at night, but that she "should" be able to go the whole night w/o eating because she was a huge 6m old (my response: so, since she's "so huge" wouldn't she need to eat MORE frequently at night?)
We switched to a different office for 6 to 15m. I was told at our 12m appt that nursing beyond a year had no nutritional value "despite what those LLL people will tell you." When I argued, she told me that really it was only good for people in third worlds, but here in America we had access to such good food that it wasn't necessary to continue. That office also had a handout for FOUR MONTH OLDS about CIO and separate sleep and ceasing night feedings.
We left for a totally separate family practice after that.
FWIW - I delivered her at the umich hospital (got talked out of my homebirth by DH, who now deeply regrets that). They took her at birth for several hours because I ran a fever in labor. They gave her 36hrs of abx after basically telling us we had an infection and that she would die w/o them. [ETA: when the cultures came back at 36hrs, of course they'd been negative.] While they had her - luckily DH was there the whole time - they continually tried to bully him into giving her formula and/or glucose water. He was so good about saying that she was breastfeeding and if they were SO concerned about her eating maybe they should let him take her back to me. I get so angry when I think that if he hadn't been so firm, they may have sabotaged the beginnings of our nursing relationship.
Moral: UM/affiliated is NOT breastfeeding friendly IMEs.
