Wee Targets

Toilet training is on my mind (for a girl, though, so this doesn’t really help…)

Wee Target zeros-in on toilet training
“Inventor Joanna Haymes, a mother of three boys, took the latter idea further and developed the “Wee Target”. Inspired by heat sensitive ink on a packet of batteries and driven to help her boys aim in the right direction, she designed a “target”- a black circle made of heat sensitive ink which is fixed temporarily inside the toilet bowl. When the target is hit by urine, the circle fades and a surprise picture appears.”
