In general, the longer your supply has been low, the longer it will take to build it back up. Get help early, before weight gain becomes a big concern. In almost all cases, once a healthy baby starts gaining weight, he won’t suddenly start losing it unless there is an underlying medical problem with mom or baby. Take care of yourself. Try to eat well and drink enough fluids. You don’t need to force fluids – if you are drinking enough to keep your urine clear, and you aren’t constipated, then you’re probably getting enough. Drink to thirst, usually 6-8 glasses a day. There is no evidence that drinking extra fluids will ncrease your supply, but it’s important for moms to stay hydrated. Your diet doesn’t have to be perfect, but you do need to eat enough to keep yourself from being tired all the time. It is easy to get so overwhelmed with baby care that you forget to eat and drink enough. Don’t try to diet while you are nursing, especially in the beginning while you are establishing your supply. You need a minimum of 1800 calories each day while you are lactating, and if you eat high quality foods and limit fats and sweets, you will usually lose weight more easily than a mother who is formula feeding, even without depriving yourself. Nurse frequently for as long as your baby will nurse. Try to get in a minimum of 8 feedings in 24 hours, and more if possible.
