A friendly reminder that unless you're exclusively pumping or are immediately returning back to work, you shouldn't pump until at least 6 weeks PP. During this time, your supply is regulating and understanding exactly how much to make for baby. if you make too much, you get an oversupply, which can lead to complications like mastitis, and foremilk/hindmilk imbalance. your baby has to be able to empty your boob on their own to get all of the milk because the milk in the front is different from that in the back. it contains different things. if you're producing too much milk, baby can't empty your breast to get to that necessary hindmilk. This information comes from the "expressions! lactation services" group on Facebook, which is ran by certified lactation specialists. I know the hospital's told you to pump at first, but you have to realize that most nurses and doctors only take one short course on breastfeeding and don't understand the serious implications that pumping too early can have.
