Why is your 12 yo so hardheaded?

At 12 years old, children are navigating the transition between childhood and adolescence, often testing boundaries and asserting their independence. This hardheadedness can stem from a desire to establish their own identity, make decisions for themselves, and seek autonomy. Additionally, their developing cognitive abilities allow them to think critically and challenge authority, which can sometimes come off as stubbornness. It's a normal part of their growth, albeit sometimes frustrating for parents.
