Whenever people said their kids play games together, without the parents, I always would look at them with wonder. I couldn't imagine the day when my kids would play a board game on their own. Let me say folks, it is slowly arriving to this house. I think part of the issue is Abigail doesn't love board games. So as the oldest she isn't inclined to seek them out on their own. Ethan on the other hand would spend all day, every day, playing a game. Now that Naomi is getting old enough to join him these two are finding their way in the worlds of games without a parent.
No, the rules aren't always followed but you know what - that is OK. Sibling game time, it is here.
