Over-scheduled children?

Kids' schedules are amazing. We wonder, as adults, where we get to the point of having only 24 hours in the day to accomplish 15 million things. I think we start as children. We want our kids to be well-rounded. So we enroll them in various activities. One - to get them to try different things and TWO - to figure out where their interests lie. But am I the only mom going crazy going from one activity to another? I doubt it. I have now tried to find activities that span the age differences - to streamline the number of different places I am driving during the week. The girls are in gymnastics together. The boy goes to music class while his sisters are in school That is 2 activities a week instead of 3. But my understanding is that as they get older, it just gets worse. As moms, we do our best to raise well-rounded, socially responsible, kind and gentle humans. There must be an easier way...
