I used my left breast too much today, leaving the right too full. It's so heavy with milk that my skin is pulled tight, and there are pockets of milk creating large bumps underneath. I need to pump to relieve the pressure. First, I turn so that you can see the bumps. Then I lift and drop each breast so you can see how heavy and hard the right one is by comparison. I press the top of my breast making milk explode out. I squeeze my nipple causing more splash before pumping out a whole bottle in less than 5 minutes.
