As to the underlined - oh please. She may not have been "Hollywood thin" for a while, but in "real world" terms there's no damn way she would have been considered overweight before she got pregnant.
You are definitely projecting from your own experiences. Just because you had a difficult time recovering from your pregnancies does not mean that most people will.
My girlfriend had her first at 33, then got pregnant again when baby was 4 months old. She recovered just fine from both, and was back in her size 4s 6 months after baby #2.
And as for early 30s being considered practically elderly in the world of obstretrics... um, maybe in 1812. But today that's just nonsense.
