Young children resist when they feel no ownership over what is happening. The need for autonomy, choice and self-agency, is real even at age 4. A task imposed without any yes from the child triggers resistance that looks like defiance but is actually a healthy drive for competence and control. Connection always comes before direction at this age. When power struggles are frequent, ask which of the three Cs has gone quiet: does your child have enough genuine choice? Is the relational connection between you warm? And does the task feel manageable and within their reach?
You get to pick. Do you want to sit at the table or on the floor? Do you want to start with the easy part or the fun part?
