Week by Week Pregnancy, Weeks 15-20

Congratulations! You are nearly half way through your pregnancy now! During weeks 15 and 20, your baby will grow from 4 inches to 7 inches and more than triple his or her weight from 2.5 ounces to 10 ounces! Your baby will grow from the size of a naval orange to that of a banana!

During this time, your baby's nervous system will rapidly mature as nerve connection between his or her brain and lower extremities develops. Read and sing to your baby, as sensory development of hearing is in full swing!

Around 18 to 20 weeks of pregnancy, two very exciting milestones will occur! First, you will feel fluttering, as your baby moves about, called "quickening." And, upon sonogram, your baby's gender can be revealed!
