new to ep'ing please advise!

Hi my daughter was born 2 weeks ago with a cleft palate and cannot latch. I've been pumping for her since day one and usually get about 25oz from 8 pumps. I'm wondering when supply will pick up and more importantly when/how to drop pumps. I hate the middle of the night ones. But if I sleep for 4 hours I wake up engorged and leaking like crazy. How do you get to a place where you're making more milk and can drop pumps to sleep?
