Parents of children approaching kindergarten age often wonder if their little tyke is really ready for this big step. Frequently they turn to others for an answer -- family and friends, their pediatrician or, if their child attends preschool, his preschool teacher. But in the end, no one knows a child better than his own parents. So don't let the question of readiness intimidate you. You're fully capable of making a determination. All it takes is a bit of observation and an honest assessment of your child's behavior and activities.
