We started to have our son participate on making decisions on purchasing new appliances… as an exercise for him to get more involved in family decisions. After all, we are family, great exercise to get him more familiar with family participation and involvement. Like playing, very soon started what ur used to be a game, to a great interaction snd important decision maker in the family.
He started to turn off the lights in the rooms we were not active. He turned into our automatic turning off lights after we left (for example), for dinner.
