Milk supply is a common concern among breastfeeding mothers. While many moms are worried that they're not making enough milk, an oversupply (or more milk than the baby needs) can have it's own set of problems.
Some women simply make more milk due to genetics and biology (like an overactive thyroid). However, the amount of milk someone produces is greatly influenced by how often and how long the baby nurses and how much a breastpump is used. For example, if a mom produces a lot of breastmilk in the beginning, the feeds might be shorter and more frequent, so that the baby doesn't empty the breast, and mom has to pump for comfort, which leads to making more milk.
Sometimes an oversupply happens when moms are pumping in between feedings to build up a stash of breastmilk.
An oversupply doesn't require medical treatment, but here are some things you can do to adjust your supply levels:
