Same here. Timeout for everyone. When you are done crying and settled down you can come out.

I don't use the playpen though. I don't want a child to dislike their playpen so it is never used for punishment. I have a spot on the floor by my laundry room door. Or if outside they sit by the door at the house. I actually had one boy put himself in timeout when he got upset. It was hilarious. He knew that was his spot to pout/feel mad/calm down.
