V.D.
You can also take an herb called Lactate Support or Fenugreek seed to increase milk supply. I heard that sometimes the pumping amount can be different than what the baby is drinking. My lactation consultant would have me weigh the baby naked. (then put a diaper on to breastfeed) Then breastfeed, then weigh the baby naked again. The difference in weight would be how much he drank.
Oh- while taking the fenugreek you will smell maple syrup. It's normal!!!!!!!!
