Kids, what to do with them?

Have you ever watched a young child test the people around them to see if they get in trouble? I was watching my grandson one day & he was sneaking over to the cd case, which he knows he can't play with. He would look around & make sure everyone saw him & then he would go into action. he would reach ever so slightly toward the cds & wait until somebody stopped him but when nobody did stop him he would gently grab a cd & look around to make sure the coast was clear & he was out of trouble. When I would say "no", he would stop & look bewildered even though he knew exactly what he was doing & then he would back away. He appeared to be testing the adults in the room not unlike a dog on an electric shock collar. The dog approaches the boundries of the invisible electric fence & when it gets zapped it stays away but as soon as the dog can sneak by, he is gone. I think kids are the same way. they don't really care about what they are playing with because for heavens sake, they can play with a card board box for hours. They want to test the boundries & see what they can get away with & it's not just little kids, it is teenagers and adults also. The only difference is that when kids get older the range of safety get's more complicated & the importance of what they test is much more critical, so be consistent & make sure your boundries are very clear. You may not fix all the worlds problems with this but you will have a more defined relationship & you will be respected for having boundries which are very clear.
