The girls have taken to counting things to make sure they have an equal number. This usually happens when they really like something (think candy or chips) or really don't like something (think some vegetables). The counting drive me and Daddy crazy.
To stop it, we came up with a new rule. If you count, we change the number of items. If it's something you like, we take one away. If it's something you don't like, we add one. When you tell on your sister for counting, we do the same.
I'm sure they are still couting, but at least now they do it quietly. I'll take that as a compromise.
