Picture of Second Trimester (20 Weeks)

Your baby is more active. You might feel slight fluttering.
Your baby is covered by fine, downy hair called lanugo (luh-NOO-goh) and a waxy coating called vernix. This protects the forming skin underneath.
Eyebrows, eyelashes, fingernails, and toenails have formed. Your baby can even scratch itself.
Your baby can hear and swallow.
Now halfway through your pregnancy, your baby is about 6 inches long and weighs about 9 ounces.
