Thanks ladies. I will be open for my 1 year mark on September 01st 2014. So from what you have all said I have 2 questions:

1) Do I raise my rates at MY 1 year mark or when the family started year mark?
2) Many of my part timers are b/a school students, and I charge by the hour. Do you think a $0.50 raise per hour is fair? Most are here for a combination of 2 hours a day, so that would equal to be $1 raise per day.
