25 weeks

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

How your life's 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 thanks to hormonal changes, the hair that you'd normally shed is sticking around longer than usual. Enjoy the fullness while you can — the extra hair will fall out after you give birth.

You may also notice that you can't move around as gracefully as before. Unless your caregiver has advised you otherwise, it's fine to continue to exercise, but follow a few safety rules: Don't work out when you're feeling overly tired and stop if you feel any pain, dizziness, or shortness of breath. Don't lie flat on your back and avoid contact sports as well as 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.
