Your Pregnancy Week by Week: Weeks 35-40

Week 35

Baby: Your baby measures about 20.25 inches from head to toe and weighs more than 5.5 pounds. Lungs are almost fully developed, but if born now the baby would probably be put in an incubator. It still doesn't have enough fat deposits beneath its skin to keep warm outside your womb.

Mom-to-be: Your uterus is about six inches above your navel. By now your weight gain is probably between 24 and 29 pounds. Your doctor will test you for Group B streptococcus bacteria between now and 37 weeks. You may be getting more uncomfortable and not sleeping very well. You also may be getting more anxious about the labor and delivery, and you may even be moodier and more irritable.

Tip for the Week: Be sure you've collected the necessary baby clothes, equipment -- especially a car seat -- and furniture to get you through the first few weeks, at least.

Week 36

Baby: Your baby measures about 20.7 inches from head to toe and weighs about 6 pounds. The baby may drop lower in your abdomen, usually assuming the head-down position after having frequently assumed other positions during early pregnancy. The brain has been developing rapidly, and your baby is practicing blinking.

Mom-to-be: Your uterus has grown bigger these last few weeks and is probably up under your ribs. But you're in the home stretch; after this week you'll be seeing your doctor weekly. You may be alternating between fatigue and extra bursts of energy. You may also be experiencing increased backache and heaviness, constipation, heartburn and discomfort in your buttocks and pelvis.

Tip of the Week: Start stocking your freezer with foods that can be easily popped into the oven or microwave after you bring your baby home. Chili, casseroles and many other dishes can be prepared and frozen ahead of time for use later.

Week 37

Baby: Your baby is about 21 inches from head to toe and weighs almost 6.5 pounds. Baby is getting rounder every day, and skin is getting pinker and losing its wrinkly appearance. Baby's head is usually positioned down into the pelvis by now.

Mom-to-be: Your uterus may stay the same size as it was for the last week or two. Your weight gain should be about as high as it will go, about 25 to 35 pounds. About this time, your doctor might perform a pelvic exam to help judge the progress of your pregnancy.

Tip of the Week: Just in case you deliver early, consider packing two bags for the hospital. Pack one bag for you, with warm socks, a robe, lip balm and everything you'll want during labor. Pack the other bag with the newborn items you'll want after your baby is born.
