Baby Bump: Weeks 33-36

Week 33

He is beginning to run out of space to move in the uterus and is tucked into the fetal position. His movements in the womb may be less frequent as a result of cramped space, but he is growing and delivering stronger punches and kicks. He will have periods of deep sleep and periods of being actively awake, much like a newborn baby.

Week 34

Your baby is approximately 16-18 inches long and weighs 4-5 pounds. Her arms and legs are continuing to fill out from fat accumulation. She's dimpling at her elbows and knees and forming creases around her wrists and neck. The percentage of fat on her body is eight percent, compared with only one percent of her body weight at 20 weeks. At birth, her body fat will be about 15 percent, helping her to keep warm.

Week 35

As your abdomen stretches thinner, light is visible inside the womb, helping your baby to develop sleep cycles, reactions and responses to her surrounding environment. As he grows and the space gets tighter inside the uterus, his foot, elbow, or other little body part may be visible under the skin of your belly.

Week 36

Your baby is approximately 18 inches long and weighs 5-6 pounds. Your baby will be descending even lower into your pelvis; this is called "lightening" or "engagement." As your baby rests her head in the pelvic cavity, your lungs and stomach are less pressured, possibly making breathing easier. Usually, by this point in the pregnancy, a boy's testes have completely descended.
