Picture this. Your 5 year-old son is playing with figurines in the lounge room. The toys are scattered over the floor. Your parents-in-law are coming over soon. You'd like the floor cleaned up.
Or this. Your teenager is going to a party, and you've offered to pick her up at 11pm, as you have to get up early the next day. She wants to stay until 12am.
In each case, you'd like your child to change their behaviour.
How will you get your child to change? What will you do to motivate him or her? And importantly, will you maintain a relationship of mutual respect?
