Sorry there is no Biography!
On the set of Problem Child 2, eight year old Ivyann Schwan entered a bathroom during filming. Earlier she had been told to immediately come out of the bathroom, and continue her run.. but she never left the bathroom this time, leaving the crew and cast waiting.. and waiting. The director called her name. No answer. He called again. Again no answer. As soon as everyone was ready to walk in, they heard a small voice - slightly irritated - return that earlier call. "Hey I'm on the potty", she exclaimed.
