Gradually shifting to the same position in which 95 percent of all babies are born, your baby starts to move into a head down pose, known as the vertex position.

Your little one is now up to eighteen inches long and as heavy as a five-pound sack of flour. The rest of her body is finally catching up to the size of her head. Although it may feel like your baby is constantly up and about, she's actually sleeping 90 to 95 percent of the day, a figure that will drop only slightly when she is born.

If your child were born today, she'd have an excellent chance of surviving and eventually thriving outside the womb. However, she'd still be considered preterm or premature, just as any birth before thirty-seven weeks of gestation.
