Anyone else feel like they don't have time to pump as often as they planned to?

I'm exclusively pumping. I try to pump every 3 hours but it rarely works out that way lately. It ends up being every 4-5 hours now. I have a young toddler AND a 3 week old. Even with the help I have now, I don't have much time to pump. So many things get in the way. I get around 3-4 oz each session, and I feed formula at night. So I have more than enough breastmilk. I even have some frozen.
