Think about whether your foster child really knows the socially appropriate ways to behave. Remember, this takes time. Just telling him is not nearly enough. He needs to try, behave inappropriately, try again, and maybe do it wrong again. Like other children, he also will sometimes act badly even though he knows better. You are looking for successive approximation. This means he comes closer to what you want as time goes on. No one always behaves well. Your goal is only for him to act more appropriately more of the time.
