Fetal development in pregnancy week 20:fetus in fifth month This week you're carrying about 10.5 inches and 10.5 ounces of solid baby-miracle-goodness! Their little delicates bones continue to ossify and toughen while their itsy bitsy finger and toe pads are finishing up. Your little monkey now has teeth buds, although they’re hidden beneath the gum line. And finally! Their limbs have reached their relative proportions—no more alien baby! Their cute pink lips are more defined, and might be helping out in a bit of prenatal thumb-sucking. If you have a little boy, then their tiny testes are descending, though they have not yet passed the abdominal wall. What’s more, eyelashes and eyebrows are also visible. At this point, your little one really looks like a miniature baby—and we do mean miniature as your little swimmer currently weighs a mere eighth of their final birth weight. With half the pregnancy behind you, the most significant gains are yet to come!
