Pregnancy Week 29 - Baby's Muscles & Lungs Maturing

At 29 weeks, your baby is about the size of a butternut squash. The muscles and lungs are maturing, and your baby is becoming stronger and more coordinated in movements. The bones are fully developed but still soft and flexible for the journey through the birth canal.

Baby Development This Week

Your baby's muscles and lungs are continuing to mature. The bones are fully developed but remain soft and flexible, which helps during birth. Your baby is getting stronger and more coordinated, and you may feel more distinct kicks and jabs. The adrenal glands are producing hormones that help regulate body functions. Your baby's head is growing to accommodate the rapidly developing brain. The skin is becoming smoother and less wrinkled as more fat accumulates.

Changes in Your Body

You may be feeling increasingly uncomfortable as your belly grows. The top of your uterus is now about 3.5 to 4 inches above your belly button. You might be experiencing heartburn, indigestion, and constipation more frequently. Some women feel their baby's movements more strongly and may even see their belly move. You may need to urinate frequently again as the baby presses on your bladder. Difficulty sleeping is common, and you may experience vivid dreams or pregnancy insomnia.
