If your hands or wrists suddenly ache, consider this: Doctors say carpal tunnel syndrome is a common problem among expectant and some new moms. "Water retention during pregnancy can put pressure on the median nerve in the wrist," says Christine Muhleman, president of the American Society of Hand Therapists. "Though most carpal tunnel cases get better on their own after delivery, for some new moms, holding or picking up the baby in a way that puts stress on the thumb or wrist can increase the risk of irritation to the tendons in those areas." To prevent hand and wrist pain before and after pregnancy, follow these tips:

• Check your posture. Hunching forward during tasks can cause you to hold your hands in an awkward position while typing or writing, stressing nerves and tendons.
• Pick up bags better. Lifting a heavy briefcase or diaper bag can strain tendons in the elbow. To bear the weight better, get close to the object, hold your arm near your body and lift with your palm facing up, using your biceps for support.
• Keep wrists straight. When holding or rocking your baby, try not to bend your wrists. Put him in the crook of your arm rather than near your wrist, or sit with him in your lap to relieve your arms.
• Use a nursing pillow. You'll reduce strain and tension in your shoulders, arms and hands while nursing.
• Don't brace yourself. If you have persistent pain, don't get a splint before consulting a doctor or a hand therapist. It may prevent you from finding out what's causing your pain and may even exacerbate it.
