I do know that Kathie Lee Gifford had the liposuction after her daughter was born. I watched the show after she returned (from maternity leave) and she was talking about after the OB was done (can't remember if she had a c/s), then the plastic surgeons came in, and did their work. I was like "wow! must be nice!!" Never really watched her after that, because she made me sick.
I do agree that most OB's put that thought in the mother's head about having a big baby. My friend was expecting #4, and her #3 had been almost 11 pounds. I think her #2 was 10 pounds. Anyway, both babies "got stuck", and had to be forced out with forceps or something. So, when she was going to have #4, the doctor measured the baby with u/s, and said this baby was going to be a whopper, and that she needed to schedule a c/s. She did, baby was born a healthy 8 pounds 6 ounces.
My mom is 5'4" and weighs 120 at the most when pregnant. She had 7 natural deliveries (and 1 c/s in 1971 due to a stupid doctor, and then really blotched her scar...she should have sued, but it was a military doctor back in 1971. Had 6 naturals afterwards), and her #6 and #8 were both almost 10 pounds! Her smallest baby was #4 and she was 7 pounds 3 ounces! I think I was her next smallest at 7#12.
