Switched to pumping!

I have an 11 day old & I was only breastfeeding until about 2 days ago. It just got to hard with not being able to just hand his dad or anyone a bottle so I was getting nothing done on top of almost zero sleep! So far so good with the 3 oz bottle feedings. I been breastfeeding through the night though. I'm still getting the hang of a pumping schedule & milk storage. I've only been getting 2 oz from both breast with about 25-30 minutes of pumping. Is that normal? Today I got 4 oz from both breast though, so that's the most I've gotten. Any tips are welcome! :)
