I hate when I have to be the referee because it usually never ends on a happy note. One boy usually end up hurt..... angry that their brother got the best of them. Ugh--- what happened to the good ol' days when boys just played marbles? ;)
Andrew and Jonny will wrestle all day if I let them, but I often direct them to go and play something else unless they both just want to go to their room and takes naps instead.
Then they get goofy on me!
