Some people can pump out ozs others only a few drops, but both manage to sucessfully feed. It depends when you express, your supply will be more abundant in the morning. I only leak a little now when I let down, out of the breast that DS isn't feeding on, however in the beginning I'd leak quite a lot.
How often are you hoping DH will be able to feed your LO? Is it to give you a break or to bond, as there are plenty of other ways for him to bond with baby that don't include feeding i.e. bathing, changing, cuddles, taking them out for a walk so you can get a bit of rest and a nice bath etc.
