28 weeks

How your baby's growing: By this week, your baby weighs a little over 2 pounds and measures about 14.8 inches from the top of her head to her heels. She can open her eyes — which now sport lashes — and she'll turn her head toward a continuous, bright light from the outside. Her fat layers are beginning to form, too, as she gets ready for life outside the womb.

• 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:

Do your legs feel creepy-crawly at night? Tingling in your lower legs and an irresistible urge to move them is known as restless legs syndrome (RLS), and it can make it hard to relax when you're settling in. No one knows what causes RLS, but it's common among pregnant women. Try cutting down on caffeine, which can make the symptoms worse, and massage your calves when they feel tense. Some studies also show that taking iron supplements helps ease your discomfort.
