Q: I know kids need privacy as they grow up, but how old should my child be before I start knocking on his bedroom door when I enter?
A: Unless safety is an issue, always be respectful of your child’s privacy. Generally, once he’s in elementary school, knock and ask permission before going into his room, and expect him to return the courtesy. Also, remind your kid that privacy carries obligations. Let him know what’s acceptable behind his door, whether it’s clothes on the floor, or dirty dishes on his dresser.
