Heading into Week 34

How your baby's growing: Your baby now weighs about 4 3/4 pounds and is probably almost 18 inches long. His fat layers — which he'll need to regulate his body temperature once he's born — are filling him out, making him rounder. His central nervous system is still maturing and his lungs are well developed by now. If you've been nervous about going into preterm labor, you'll be happy to know that 99 percent of babies this age can survive outside the womb — and most have no major long-term problems related to prematurity.

How your life's changing: You may be feeling a little fatigued lately, and that's perfectly understandable. Let yourself slow down and save some energy for labor day. If you have to spend a lot of time on your feet, try wearing a maternity belt that supports your abdomen and helps redistribute some of the weight. And if you've been sitting or lying down for a long time, don't jump up too quickly. Blood can pool in your feet and legs, which may cause a temporary (but rapid) drop in your blood pressure and make you feel dizzy when you get up.
