At 29 weeks your baby is approximately 15 inches from head to toe, and weighs almost 2.5 pounds(about the size of a butternut squash).
Your baby's muscles and lungs are continuing to mature, and it's head is growing bigger to make room for it's developing brain. The skeleton hardens even more and the brain, muscles, and lungs continue to mature. Nearly all babies react to sound by 30 weeks.
Note: Every baby develops a little differently — even in the womb. This information is to give you a general idea of your baby's size.
