Your child's ability to manage big feelings—staying calm when frustrated, handling transitions—matters just as much as knowing their ABCs. Research suggests that kids who can regulate emotions do better socially and academically in kindergarten and beyond. The good news? You can teach this skill right now. Simple strategies like naming feelings ("You're upset the block fell"), deep breathing, staying calm yourself, and playing together all build emotional control. Look for preschools and community programs that focus on social-emotional skills alongside academics—ones where teachers actively involve parents in strengthening your child's self-control. Starting now gives your child a real advantage as school approaches.
