25 Weeks Pregnant

Your baby-to-be's lungs are developing rapidly, although she'd probably need a little help breathing if she were born at this point. Her respiratory system continues to develop, her nostrils are open, and she can breathe—but she won't take her first breath of air until delivery day. By your 25th week of pregnancy, her reproductive organs are formed (in boys, the testes have descended). Her skin is translucent and wrinkled, and she can hear your stomach when it gurgles and your voice when you sing. Your baby is becoming more aware of how she can move—she's wiggling her fingers and toes!
