You need 1,000 milligrams of calcium every day to build your baby’s teeth and bones. Not getting enough could harm you, too. “Inadequate calcium intake may cause bone loss and tooth damage in mothers,” warns OB-GYN Sharon Sutherland, M.D., an assistant professor at Cleveland Clinic Lerner College of Medicine of Case Western Reserve University in Ohio.
That’s because your body drains calcium from your bones to strengthen the baby’s, which could lead to osteoporosis as you get older (see “Osteoporosis Prevention").
