*I* did not call her "fat" or "a cow". I said she was overweight. And she is. So what. I don't think those pics are truly representative of her weight over the years. She struggles. A lot. And goes up and down the scale. A lot. All it means is that she probably isn't as fit or thin as those who seem to bounce back from pregnancy effortlessly.
She'll probably do just fine with her close-together pregnancies. I don't think she's fully recovered from her surgery yet though, and it would have been wiser to wait a few more months or a year to fully heal and replenish maternal nutritional stores. Not doing so will probably set her back a bit with her next recovery. It's her choice though.
