Re: Surely I didn't screw up my supply?
Just once shouldn't be a big deal.
It's hard to get a grasp on how the logistics of supply and demand work because they're so individual. A lot depends on storage capacity. Mamas with big storage capacities can hold a lot of milk for a long time without having it impact supply all that much. Mamas with smaller storage capacities can't let milk sit unused in their breasts for very long without seeing supply go down. You can't tell just by looking what kind of mama you are: big breasts don't necessarily store more milk than small ones. And I think that storage capacity probably changes with time, which complicates the picture even more.
