I may as well have all the bad news. You could become depressed and frantic because of weight gain during pregnancy. You might feel so out of control of your life and body that you would try to hurt yourself or the unborn baby. You might worry and feel guilty about the damage you could be causing the baby. You might underfeed your child to make her thin, or, you might overfeed her to show the world that you are a nurturing parent.
Power struggles over food and eating often plague families where someone has an eating disorder.
You could continue that pattern with your child. This gets worse and worse, but I have a lot of love in my heart. I think I would be a good mother. The eating disorder wouldn't be that important if I had a child. Motherhood is stressful.
