Although the boys in your Pack are all kids, they are not all young kids. The boys in your Pack probably range from 6 to 11 years old.
There is a lot of difference between 6 and 7 year olds and 10 and 11 year olds. Some activities that are a lot of fun for the boys in your Tiger and Wolf dens would be way too young and kiddie-ish for your Webelos boys. It’s not a great idea to have your entire Pack doing an activity that will make your Webelos feel like they are back in nursery school. For example, singing “I’m a Little Teapot” can be a lot of fun for your Tigers, but if you make your Webelos join in many songs like that, they may just look at each other and say “We’re too old for this.” and not come back.
One of the great things about putting on a Cub Scout program is seeing how much boys grow and develop from the time they are first grade Tigers until they are fifth grade Webelos. Be sure most of your Pack activities are designed for the interests and needs of all your boys.
