I just completed a small CHK reorganization to nest all activity lists on one main-menu page, Activities and Classes. On this page, you will find descriptions and links to lists for Parents and Parents-to-Be, Babies (under 1 year old) and Toddlers/Preschoolers (1-4 years old). Also see All the Free Things, a list of no-cost activities for all age groups.
A list for elementary age is coming soon. Comments? Email email@example.com.
