Hanging On to Healthy Pregnancy Habits -- For Good!

Pregnancy keeper: Lots of water

Why: Dehydration is the number one cause of fatigue, says Waterhouse. We drink about two glasses per day, but our bodies need six to eight.

Good habit helper: Always carry a water bottle with you, even around the house. Remember that the caffeinated beverages you cut back on during pregnancy are actually diuretics (they dehydrate), so don't replace water with cola or coffee.
