I have one that is 18 months and just started into this behaviour. He gets his boots and throws them at mom. He goes to my front door and bangs on it. When asked to put his coat on it's a nice big "NO" as a response. He's fine all day with me and rarely says no to me. And if he does he certainly doesn't follow through.

This same boy goes home and is a nightmare lately apparently. He won't go into his high chair. He hits his head against the wall. Throwing full tantrums on the floor when he doesn't get his way. A completely different child.

I think it's the sign that I do my job. I have a good handle on the kids in my care and I'm consistent with my rules. They're happy, they listen, there's order to my house (as much as there can be with 5 little ones running around)

I rarely step in and correct the behaviour. As soon as mom comes in the door my magical powers disapear and no one listens to me.
