Positive Reenforcement has to be done after something positive is done. Trust me, my sister took a Child Psychology course and told me a bunch of stuff in it. Small kids must be first shown kindness so they see you as an ally, then negativie reenforcement is used to show them what they can and can't do. After the child knows right and wrong, you bust out the positive renforcement. After the newbies do something correctly and stop being annoying, then I reenforce them positively.
