I've been working on a conditional love system where I only look my children in the eye if they excell in a sporting or academic context - hugging them when they score a goal or get an A etc.
a nasty habit to get them into - better to reward spontaneously or they'll only ever react to prizes.
Star chart is a good way to motivating your children, but I'm always concerned that the child will always expect a reward for everything that he/she does. What's your opnion on star charts?
