Fun and Games Until.....

We have been cooped up at home for 2 days. Between MLK Jr. Day and a Snow Day, we are prisoners in our own home. We've played games, watched a movie, done crafts, performed a puppet show and read books. And fight. The kids start out playing nicely until someone does something and someone gets hurt. Then the crying, blaming and defending begin. I separate them and attempt to discover who is the victim and who is the culprit. There is never one clear answer. So, after the 3rd injury in 1 day, I built a Chinese Wall. They cannot play together or be near each other for the rest of the day. I calmly explained to them that it clearly isn't safe for them to play together. Someone keeps getting hurt. No matter where or what they play. I can ignore squabbling and fighting over toys, turns, snack size, etc. But when injuries occur repeatedly, I have to draw the line. Right down the middle of my house. Anyone have a brilliant solution to keeping an 8 year old girl and 4 year old boy safe from each other in their own home - that doesn't involve a jello pit and a cover charge?
