What is happening with B.B.H. at 25 weeks?

Head to heels, your baby now measures about 13 1/2 inches. His weight — a pound and a half — isn't much more than an average rutabaga, but he's beginning to exchange his long, lean look for some baby fat. As he does, his wrinkled skin will begin to smooth out and he'll start to look more and more like a newborn. He's also growing more hair — and if you could see it, you'd now be able to discern its color and texture.

Get ready for pat-a-cake! Baby's hands are now fully developed and he spends most of his awake time groping around in the darkness of your uterus. Brain and nerve endings are developed enough now so that your baby can feel the sensation of touch. That doesn't mean he can feel it when his father pokes your stomach, however, so tell him to knock it off.

Other highlights include:Your baby's arms and legs have grown to almost the proportions they will be at birth, which is still sort of short. So don't be alarmed when your newborn's arms barely clear his waist. Baby's nostrils, which have been plugged up until now, clear out (like he's taken a super-dose of Sudafed) and he can practice breathing through the nose. The structures of your baby's spine are now made up of 150 joints, 33 rings and some 1,000 ligaments. Can you believe you're growing something that complicated inside of you?The capillaries, the teeniest blood vessels, are now forming in your baby's body, giving his formerly translucent skin a pink glow.

The blood vessels in the lungs also develop this week. You'll see how well that worked out when your baby gives those lungs a workout while you're on line at the bank in a few months. Your baby weighs about a pound and a half and is about 13½ inches long—roughly the length of one of those recorders you played in elementary school music class. Who's up for a round of "Hot Cross Buns?"
