29 Weeks

At 29 weeks, baby is the size of an acorn squash. Your 29 weeks baby already measures about 15.2 inches long. And he or she weighs about 2.5 pounds, but still has a way to go—can you believe baby will triple in weight before birth?

Though she's getting pretty close to her birth length, she still has to chub out a bit. In fact, over the next 11 weeks, she'll more than double — or even come close to tripling — her weight. As more fat is deposited under the skin surface, her wrinkled skin is smoothing out. This white fat, as it's called, is different from the earlier brown fat your developing fetus accumulated. Brown fat is necessary for body temperature regulation, while white fat (the same kind you have, Mom) actually serves as an energy source.

Counting Baby's Kicks

Since space in your baby's living quarters is now at a premium, you'll be feeling jabs and pokes from elbows and knees, mostly. And they'll be more vigorous (and also less erratic) than before 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. That means 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).
