Re: Pumping no milk....
What you describe sounds very normal. Most moms can pump out a ton of milk in the early days. But eventually their milk supply adjusts to meet baby's needs very precisely. At that point, it typically becomes harder to pump because there's not a lot of extra milk sitting around in the breast.
I'd try pumping every day at the same time. The additional demand should eventually train your body to make more. Persistence is key!
