Q: What's my baby doing when I feel her move around in my belly?
A: “The first thing a baby does is big body movements, such as flexing and extending the arms and legs,” says Jennifer Keller, M.D., assistant professor in the department of obstetrics and gynecology at the George Washington University in Washington, D.C. Hiccups begin around 11 weeks, as the neurological system develops, but you won’t feel the rhythmic, recurring jerks that signal them until much later. Some women may be able to perceive big movements, such as when the baby switches positions. If you’ve been feeling pain in your rib cage and then suddenly it’s gone, it’s likely your baby was in a breech position with her head sticking into your ribs and she did a 180 to get ready for delivery.
