We once included a 5-year-old brother in our Tiger den. He did everything the Tigers did. We recognized him with rewards of dollar store items. We also had my daughter (a Girl Scout) who was about 10 at the time babysit little ones during den time. We provided her with crayons and coloring pages. She also played children's card games, and other activities with them. They were given their own space in the schoolcafeteria where we met so we could always see them. She did this for about 6 years.
