is it enough?

I've been back to work since mid-August and pump at work 3 times a day 8, 12:30, 3:30. I get between 2-3 oz. per session so on average about 9 oz. a day while I'm at work. But, I know my LO drinks at least 12 oz. a day at daycare. I'm starting to worry about having enough BM to keep up with her. I do get a little extra from weekend pumpings and I had a descent stash before I went back to work, any advice to increase my supply? Or maybe this is normal.
