Although breastfeeding brings with it many questions, one of the biggest concerns for most new mothers is whether their supply is sufficient to nourish their baby. As always, if you have any concerns about your supply, always consult your doctor. There is no website, book, or piece of friendly advice that can replace the knowledge of a medical expert.
However, if you know that you are having a supply issue—either because the amount of ounces you’re pumping has decreased or because your baby is not gaining weight (consult your doctor to know for sure)—pumping can help increase your supply.
