Who and how weaned the breast? What should be done with the breast? My doctor ordered me to wean slowly from the breast ?, so that the baby would start eating food and eat less breast milk, as my weight and my body condition simply goes down. The vitamins have all dropped, the weight has fallen to 39 although I eat 5-6 times a day and still snack. Before pregnancy I was 46-52. Now many wean earlier and nothing children are alive and healthy
