Code Word

I love my class, I really do. Having had a rough year last year, I appreciate all that this current class has to offer. Today one of my boys had an accident on the floor. Not just an accident, a Number 2 accident. The other kids smelled it, though they were either being very sweet and pretended not to know what happened, or they fell for my "he got sick" storyline. I ushered them out after covering up the mess. The boy's mom said this happens sometimes, and could we have a code word for when it is about to happen. The code word is "I have to go to the bathroom right now!" or "Emergency!"
