This statement, while said with good intentions, actually has the opposite effect you’re hoping for. Most parents say this as a way to boost a child’s self-esteem. Unfortunately, it has quite a different effect. When children hear “good girl!” after performing a task you’ve asked them for, they assume that they’re only “good” because they’ve done what you’ve asked. That sets up a scenario in which children can become afraid of losing their status as a “good kid” and their motivation to cooperate becomes all about receiving the positive feedback they’re hoping for.
Instead, try “I appreciate it so much when you cooperate!” This gives children real information about what you’re wanting and how their behavior impacts your experience. You can even take your feelings out of it entirely and say something like, “I saw you share your toy with your friend.” This allows your child to decide for himself whether sharing is “good” and lets him choose to repeat the action from his internal motivation, rather than doing it just to please you.
