Would you ever comment on your child's weight?

So my mother loves to comment on my weight. Last year when I came home to visit I was too skinny and needed to put on weight.  Now I come home and now she says I've put on too much weight. She keeps saying I need to lose weight and any time I try to eat something she gets upset and starts yelling about how I can't be eating right now. It's honestly making me feel really bad and I've told her multiple times to stop and she doesn't. So I'm curious if other moms would do that same. Personally I would never do that to my child. I mean if it gets to a point of being a medical issue then yes I'd step in but not mention it over a few pounds. Anyway what do you think about the question?
