Does anyone know if there is some kind of tablet or something similar that will turn colour once the child has done his or her duty..can't always be sure they went..with all the singing and babbling they are doing!!!!
You could try a little blue food coloring and see if it turns green.....
Add food coloring to the water. It will change with their yellow pee.
I don't know about a tablet, but they have toliet bowl cleaners that you put in the tank and they turn the water blue for a couple months. If your child has peed, the water would then look green instead of blue.
What about lying a paper towel on the surface of the water. I would think you'd be able to see a little color on it if they went.
