I found using a small notebook charting times and types of bathrooming that everyone had to write in helped too. My son wrote on the front...."Lilly's Bowel Movements"

)
I couldn't seem to keep track of when she had gone out last. I finally got everyone to write down the time and what she did (1 +/or 2) when she went out. Lessened some of the stress of the whole situation.
