Breastfeeding mothers are always advised to drink to thirst in order to maintain good milk supply and for overall hydration purposes. However, during the winter months it can be tricky to gauge whether you've had enough water. A good rule of thumb is to drink the amount of water equivalent to half of your body weight. Therefore, if you weigh 130 pounds, you would drink about 65 ounces per day. This may sound daunting to many, but not to worry. As most nursing mothers can attest, breastfeeding increases thirst substantially so oftentimes listening to your body's thirst queues is all you need to do.
