It takes a woman's body 2 full years to completely recover from pregnancy and birth. It takes this long to also recoup the lost minerals and vitamins that are taken to support a pregnancy and breastfeeding. Women have babies back to back all the time but that does not mean it is healthy for her. Yes, she is doing harm to her body. But ultimately it is her decision. And many times doctors don't tell women to wait. If they did that he/she would lose money. Remember being a doctor is a business.
