If I pump and empty both breasts, how long till they start to fill up/become full generally?

They always have milk the more you hydrate eat right and breastfeed the better your supply will be

@chelli, Im trying to empty them. I start bartending in a few weeks and the uniform is kinda... sexy?? I don't want to leak or be engorged and be too slammed to pump

They have thin breast pads and your boss should allow you a few minutes to pump while at work

You will probably wanna pump every three hours

Definitely pump every 3 hours
