Baby Bolin: 25 weeks

Head to heels, Baby Jeffrey now measures about 13 1/2 inches.

His weight — a pound and a half — doesn't sound like much, 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. His hair is probably recognizable now (in color and texture), although both may change after he's born.

How mom's life is changing:
Your baby's not the only one with more hair — your locks may look more full and lustrous than ever. It's not that you're growing more hair, but the hair you'd normally shed is sticking around longer than usual.

You probably can't move around as gracefully as before. It's fine to continue to exercise, but use your common sense: Don't work out when you're feeling overly tired, and stop if you feel any pain or when you begin to feel at all fatigued, dizzy, or short of breath. Don't lie on your back too long or do any exercise where you're apt to lose your balance. Be sure to drink plenty of water, and make time for both warm-up and cool-down periods.
