Issue: You Don't Hydrate Enough New-mom solution: Thirst is often mistaken for hunger, so if you’re not hydrated you may eat more than you should. Koff suggests increasing potassium and reducing sodium in addition to drinking more water. Snack on half of a banana, add some avocado to your lunch, or sip coconut water while nursing—all three are high in potassium.
To ensure you get the water you need, Koff suggests a simple formula: “Take your current weight in pounds, divide it in half, and that’s roughly how many ounces you should drink over the course of a day.” (For example, if you weigh 140 pounds, drink 70 ounces of water, or roughly nine 8-ounce glasses.) You can also “eat” your water by consuming juicy fruits and vegetables, such as watermelon or cucumber, Behan suggests.
Staying hydrated is especially important if you’re nursing. “You must replace the fluid contained in the milk your baby drinks,” says Behan. “If you don’t, you may have trouble metabolizing and digesting the food you eat and you’ll increase your risk for constipation.”
