I think it's great that even at 12/13 they still enjoy playing games. They were playing tag with Puggy. Do your older children still enjoy playing games? Do they still enjoy running around the yard?
Mine also enjoy the computer and tablets and other things, but it does my heart good to see them outside just playing and enjoying life and each other company.
