29 Weeks: What's Happening

At 29 weeks pregnant, your baby is almost 17 inches tall now (nearly as tall as she will be at birth), and close to three pounds (a weight that will likely more than double — and may even come close to tripling — by delivery time). Her wrinkled skin is smoothing out as more fat is deposited under the skin surface. This fat, called white fat, is different from the earlier brown fat that your developing fetus accumulated. Brown fat is necessary for body temperature regulation while white fat (the fat you have, Mom) actually serves as an energy source. Which explains why your energizer baby feels so…well…energized! Space in your baby's living quarters is now at a premium, so you'll be feeling jabs and pokes from elbows and knees mostly. But those kicks will be more vigorous than before (and also less erratic) because your baby is stronger and excitedly responding to all sorts of stimuli — movement, sounds, light, and that candy bar you ate half an hour ago. 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!

Luckily, your baby doesn't have teeth yet that would need a brushing after that sugary treat, but it won't be long before you'll need to buy that first baby toothbrush! You'll recall that your baby's baby-teeth buds formed weeks ago, but now the buds for permanent teeth are forming in his or her gums as well.

And back to those kicks, who's counting? Actually, you should be. Now's a good time to start doing a kick count twice a day to make sure baby's doing just fine (plus, it's a good excuse for a rest). Lie down (preferably after a snack) and keep track of your baby's movements. You're looking for at least ten movements in an hour's time (don't forget to count movements of any kind — kicks, flutters, swishes, rolls, and so on).
