Week 28 - 30

The baby's eyelids are partially open and eyelashes have formed. The baby is gaining weight, which is smoothing out many of the wrinkles in his or her skin.

The bones are fully developed, but they're still soft and pliable.

The baby may have a good head of hair by this week.

Weeks 31-34

Thirty-one weeks into the pregnancy, or 29 weeks after conception, the baby's sexual development continues.   If the baby is a boy, his testicles are moving through the groin on their way into the scrotum. If your baby is a girl, her clitoris is now relatively prominent.

Although the baby's lungs aren't fully formed, he or she practices breathing. Your baby's body begins absorbing vital minerals, such as iron and calcium.

The layer of soft, downy hair that has covered your baby's skin for the past few months - known as lanugo - starts to fall off this week.

The baby's kicks and jabs may be forceful.

Thirty-three weeks into pregnancy, or 31 weeks after conception, the baby's pupils can constrict, dilate and detect light entering his or her eyes.
