If everything is going according to plan...

You probably have the wrong plan. Following that general rule I decide to go in and reinforce my daughters good behavior today. 45 minutes in her room doing "quiet time" - this has replaced nap - without coming out and really without incident. The reason for the silence - Dad had left a permanent fabric marker in the room. Note: it also works on plastic, wood and metal and it really is permanent. The idea of installing a wireless web cam comes to the fore again. :-)
