Being pulled in three directions. How to deal?

Saturday's are a challenging day for a single parent. They are one of two days in the week that I don't have to go to work, the house and yard need my attention, and my kids get me the whole day. Often, the kids end up frustrated with me because I'm determined to get house work done. They can't seem to understand that if we get the work done first, we can use the rest of the day for time together. Simple idea right? I remember being a kid and not understanding this thought process at all. I feel like karma has caught up with me big time. Now my kids are me when I was kid.

What I've found, though, is if I can lure them outside with me to do yard work, we always end up having amazing conversations and get lots done, even I'm the one doing all the work and they're just watching and talking with me. Being in nature is magical.
