I have just spent two weeks with my daughters and their families, including six grandchildren ranging in age from 7 years to 8 months. It was wonderful to be surrounded by family and I may even have learned something. The seven-year-olds reveled in having a cousin the same age. They built fairy houses, swam, created art projects, and slept together at night. The grown-ups didn’t need to do much except feed them and offer gentle guidance when needed.
