Doesn't this rewarding reinforcment give them the sense that they need to be good in order to be loved. Many times in the real world even if you do everything right the only reward you might get will be the one you give to yourself. If children alway expect to get something in return for being good or accomplishing something then that will be there only reason for their actions. IF we teach our children to postive action brings self satisfaction and sometime is may bring reward but that we do it because it feels good not because we want something back in return. Then their expectations will not be let down when they have accomplished something and there is nobody around to reward them. They will continue to be successful in all they choose to do. I constantly give my child praise not because they have done something right but just because or maybe they did something wrong they still need to know you are going to be there to lift them up. This will encourage them to venture out and try new things.
