You've probably already been to Staples or Target to buy all the "must-haves" on your child's school list. Part of the ritual signaling the end of sleeping late (for you and them) and the start of another school year. Yet there's one thing you need to remember. It's simple really. You know your child best. That's it. Oh, it's easy to be convinced that others know better than you do what your child needs, how your child thinks, or why your child acts or reacts as they do.
