How often do pump as a stay at home mom?

Kiki

I'm a stay at home mom who exclusively breastfeeds but I pump everynow and then to get engorgement out or pump some to stash away. How often does one pump so that supply does not go down? I pump once in the morning normally and if I get engormenet i'l pump that breast and again pump if I fed my baby a bottle. Just wondering what others do? Ty
