Hi, my name is Dana. I am a senior nursing student at the University of Minnesota. I read that you were interested in ways in which to increase your milk supply. Pumping more frequently (even waking up in the night and pumping) and increasing your fluid intake are great suggestions that you received from the lactation consultant. I am sorry to hear that these suggestions are not working for you. I did some research and found some more information on this topic.
The production of milk depends on supply and demand. Frequent nursing or pumping is essential to the production of an adequate milk supply (at least six to eight times daily) (Wong, 1999). You mentioned that you are able to get away and pump twice a day at work. Look for creative ways to get a small, private space to pump. This would possibly allow you to pump more often or longer at each session. You could also pump both breasts at once. This will decrease your pumping time, so you can get back to work. At home, try putting the baby to the breast more often. When your baby is not nursing, stimulate your breasts.
It is also important to support yor body's effort to make milk. Try to get as much rest as possible. A daily nap is a good habit to cultivate. Futhermore, housework and vigourous exercise may make it difficult to keep up your milk supply. Try to perform these activities in moderation.
Increasing your daily caloric intake is also important to maintain your milk supply. A nursing mother needs to consume approximately 2,000 to 2,500 calories per day, depending on activity level and her size. In order to produce a liter of milk a day (about what a 12-pound baby consumes), 800 calories need to be available for milk production. About half of those 800 calories will come from your fat stores, which will result in a weight loss of one-half pound to one pound per week. The remaining calories will need to come from a well-balanced diet. To find out how many calories per day you should be consuming, determine the correct caloric intake for a nonpregnant women of your body type. Then increase that amount by 400 calories a day. Another important aspect of the production of milk is consuming fluids plentifully. You should consume enough fluid to produce pale, dilute urine (Tellalian, 1999).
I hope these suggestions that I gave you will help you with your breastfeeding problems. Some books that I would suggest reading if you were interesting in more information is Nursing Mothers, Working Mothers by Gayle Pryor or Breastfeeding and the Working Mother by Diane Mason and Diane Ingersoll.
