How your baby's growing: Your baby's a bit more than 15 1/2 inches long now, and she weighs almost 3 pounds. A pint and a half of amniotic fluid surrounds her, but that volume will decrease as she gets bigger and fills out your uterus. Her eyes open and close, she's able to distinguish between light and dark, and she can even follow a light source back and forth. Once she's born, she'll keep her eyes closed for a good part of the day. When she does open them, she'll respond to changes in light but will have a visual acuity of only 20/400 — which means she can only make out objects a few inches from her face. ("Normal" vision in adults is 20/20.)

• Note: Experts say every baby develops differently — even in the womb. This developmental information is designed to give you a general idea of how your baby is growing.

How your life's changing: You may be feeling a little tired these days, especially if you're having any trouble sleeping. You might also feel clumsy, which is perfectly understandable. Not only are you heavier, your balance is off and your joints are loosened, thanks to pregnancy hormones. Those loose joints can actually cause your feet to grow a shoe size --permanently.
