Teenage is when your child is going through physical and mental changes, and a messy room may be their representation or manifestation. For a teen, their room is their territory, and they want to assert their authority. Instead of forcing or blaming them, you may set reasonable rules with an explanation. For example, no food on the bed as it might make the room smelly, or keep things in place so you can find them when you need them. Also, don’t be hard on yourself as a child’s messy room does not reflect your parenting skills.
