29 Weeks: butternut squash

Your baby can open her eyes and will turn her head towards a source of any light. Her sensory organs are well developed. Her fingernails and toenails are growing and she is beginning to regulate her own temperature. The bone marrow is completely in charge of production of the red blood cells now. Your baby even urinates about a half liter of urine into the amniotic fluid every day. Your baby weighs about 2.5 pounds and is over 15 inches long.

The movements you feel will probably begin to change at this point. You once were the home of wild gymnastics parties, but now as the space becomes cramped you will notice smaller movements, such as elbows and knees poking you.

Her muscles and lungs are continuing to mature, and her head is growing bigger to make room for her developing brain. To meet her increasing nutritional demands, you'll need plenty of protein, vitamins C, folic acid, and iron. And because her bones are soaking up lots of calcium, be sure to drink your milk (or find another good source of calcium, such as cheese, yogurt, or enriched orange juice). This trimester, about 250 milligrams of calcium are deposited in your baby's hardening skeleton each day.
