How your baby's growing: This week your baby weighs a little over 4 pounds and measures 17.2 inches from the top of his head to his heels. His skin is becoming less red and wrinkled, and while most of his bones are hardening, his skull is quite pliable and not completely joined.

How your life's changing: You may be feeling some aches and even numbness in your fingers, wrists, and hands. Like many other tissues in your body, those in your wrist can swell, which can increase pressure in the carpal tunnel, a bony canal in your wrist. Nerves that run through this "tunnel" end up pinched, creating numbness, tingling, shooting or burning pain, or a dull ache. Try wearing a brace or propping your arm up with a pillow when you sleep. If your work requires repetitive hand movements (at a keyboard or assembly line, for example), remember to stretch your hands when you take breaks.

If you're having trouble sleeping at night, try wedging a pillow between your legs and behind your back. If that doesn't help, try sleeping in a semi-upright position, with several pillows behind your head (or sleep in a recliner!). If frequent trips to the bathroom are robbing you of your zz's, cut back on fluids by late afternoon or evening.
