I started the tradition of picking wild berries in the summer when my children were youngsters. I grew up doing that in New York's Hudson River Valley. Foraging for food has a old cross cultural culinary tradition that commoners have practiced around the globe for centuries. At a young age, commoners learned how to live off the land. I encourage parents to take some time and learn from specialist in your area about what you can forage in your area. Then start a healthy family tradition like picking fresh berries and serving them over ice cream. By the way, making home made ice cream also has a old cross cultural tradition.
