This just does not sit well with me. These are 6 & 7 year olds. Never have I ever said to my son when he asked to use the restroom, "too bad, hold it." I know myself, sometimes I don't have to go and then 5 minutes later I need to find a restroom. And a child's bladder is not the same size as an adult's. This sounds punitive and cruel. My kid would be getting a note from his doctor.
