Finding time to pump

Kimberly
Anyone else findings it hard to make time to pump. My daughter nurses every 2 hours (sometimes more often) during the day. Plus I have a 5 and 8 year old to take care of. The only time I can find time to pump (once) is in the middle of the night. She nurses one side and I pump the other. That's likely not enough to keep a good supply for when I go back to work! Any suggestions from Mommas with multiple kids?
