Week 13

My Baby's Development

As you begin the second trimester of pregnancy, your placenta has developed and it starts to provide your baby with oxygen and nutrients, and dispose wastes. It also produces the hormones progesterone and estrogen, which help to maintain the pregnancy.

By now, the baby's eyelids have fused together to protect the eyes. Your baby may be able to put a thumb in his or her mouth by this week. But the sucking muscles may be not yet completely developed.

My Body

At your first prenatal appointment, your health care provider probably has given you a prescription for prenatal vitamins. Taking these supplements, in addition to eating a healthy diet, ensures your baby gets additional vitamins and minerals (such as folic acid, zinc, iron, and calcium) which are necessary for its growth and development. Consult your pharmacist about the best way to take your vitamins (such as whether they should be taken with food or beverages).
