Third Trimester: Images of Your Developing Baby

We've partnered with the American Institute of Ultrasound Medicine (AIUM), Johns Hopkins, and the March of Dimes to create this unique peak into Baby's development inside the womb. These images reveal all the intricate details of your baby's growth -- from a collection of cells to a full-term newborn. While most women may only receive one or two ultrasounds during pregnancy, which is normal, this slideshow of the 3rd trimester of pregnancy gives you a look at each week of development.

Week 28 (26 weeks from conception)

Fetal Size: Length, 10 inches, crown to rump; total length 15 3/4 inches. Weight, almost 2 1/2 pounds.

Fetal Development Milestones: Your baby now has added brain tissue and her scalp hair continuing to grow. Her eyes are opening and she's gaining weight.

What You're Seeing: Welcome to your third (and last) trimester! Your baby-to-be's hair is seen waving in the amniotic fluid. This hair is called lanugo. Unfortunately, we can't predict how much hair your baby will have because he will lose his lanugo before being born and it will be replaced with the hair we're used to seeing on infants at birth.
