7. Hold the liquid after 4 p.m.
As any potty-training mom knows, you fill your kid full of water and juice all day long until around 4 o’clock. Then you give him liquids only when he asks for them, and then in quarter-cup amounts. As a result, your kid can sleep through the night and wake up dry, rested, and proud the next day.
The same thing works with pregnant moms, says Dr. Pien. Some of those nighttime trips are due to your physiology. But there’s also another reason: Most pregnant women are busy all day long and don’t take time to drink and stay hydrated. So when they get home, they tend to tank up. The fact that they need to get up and urinate during the night is a natural consequence. A better approach is to carry a large water bottle with you all day—and finish it before you leave work.
