Childcare Needed

Four kids: 4th grade, 5th grade, 7th grade, and 9th grade. All are bright and loud. For the past few years we've had them all in water polo, which has practices in Round Rock a few nights a week. My schedule isn't too demanding, but I sometimes work afternoons and evenings while my wife's clinic can run until dinner time on weeknights. We would mostly need help with school pickup, dinners, getting to practice, and home to bed 2-3 days per week more or less. The occasional Saturday for date night would be a nice, but not required.
