Feeding routines.. For mommies who pump

So I exclusively pump every 2-3 hours and I get like 4-6 ounces each time. My little one wakes up every 2 hours to eat so I hear up the milk and feed him and then i pump and then hold my LO until he falls asleep. Takes about an hour for everything and then he's awake again in an hour to feed. Just wondering what everyone's routine is? I'm afraid to not pump at night and losing my supply. I was pumping like 6 oz each time but notice lately it's more like only 4-5.
