　　During the school year many parents take on the role of driver as they drive their children from one lesson to another. Understandably so. Many of us want our children to have a little taste of everything, from organized sports to music, dance and more. But we can overdo it, leaving our children feeling a little burnt out, and according to parent educator Diane Loisie, it’s their school work which suffers the most. “After school, if they’re busy in a number of sporting events, besides they need to do their homework, then the time they’ll feel sleepy is in the classroom. Your child needs free time. So if you’re filling up that after school time, then it’s during the day that they’re going to be taking a break.”
