Just look at the “Rain or Shine” preschools in Scandinavia, where toddlers spend the majority of the day outside all year round, playing in creeks, digging in dirt and chasing each other around the woods. Places where they hone their motor skills by balancing on logs and jumping on rocks, and bond with nature by getting their hands on bugs and plants on a daily basis. In Scandinavia, these preschools have been around for over 50 years and are a popular choice among health-conscious parents.
