I do not have children of my own but I do not see how you can say that rewards do not help. I understand that you think rewards make people lose more interest in the subject and I agree with this. However, I think that children need positive reinforcers to know that what they're doing is good. Children do not learn the way that adults do. I believe that when they do something right they should be praised. When babies are learning how to talk, we praise them and they understand that by saying a word they will get attention. This is the reason that children start talking. In most cases, if you do not praise the child and give them positive reinforcement, they will not realize that what they're doing is good. Rewards can be overdone to an extent. I think that when children are just learning to do a new task or they do something nice and out of the ordinary they, should be rewarded. Sometimes when people reward for every little step a child makes, they can take advantage of the parent but they do need rewards to know that they are doing something to be proud of.
