My baby is 20 days old. My breast milk supply is low, so we are feeding lactogen simultaneously. I am using breastpump also to get expressed milk whenever I feel heavy, but it is not enough to fill my baby's stomach. And then I feed him Lactogen. My question is whether we can mix expressed milk with lactogen milk and feed it to the baby or not? Will it cause any problem or is it okay to feed it this way?
