Any child in Kindergarten through Fifth Grade may join Cub Scouts. However, Cub Scouts is for families: moms, dads, siblings, grandparents, aunts, uncles, everyone can be part of Cub Scouts. Whether your involvement is as limited as attending meetings with your Scout, participating in planning Den or Pack events, or being a part of the Pack Committee or a uniformed leader is up to you, but it will be an excellent way to interact with and help your Scout grow.
