I used a gallon water filled bleach bottle for Peek, who at 16 YO had just learned to use the PeePads. The bottle really helped him with his balance, although I did witness a few 'Air-pee' events (think air guitar, lol). He rarely squatted. One time he was aiming on one of my antique sewing machine bases, and I looked away just as he readjusted his aim to my leg! I had stood very still bc I didn't want to do Peepee interuptus, haha, but his aim was a tad short and only hit my shoe. He had never done that, I think he may have been going partially blind at the time, or I was standing too still and he didn't realize it was my leg.
I love the idea of having 'PeePad Wallpaper'. LMBO!
