Invented by a British mother of six, My Wee Friend is a simple potty training method. It is a black disc which adheres to the bottom of a training potty. When the child uses the potty, the disc temporarily reveals a smiling face, then reverts to black. It can be left in the potty, cleaned as usual and reused for up to 12 weeks. Suitable for both boys and girls, it motivates the child and reinforces consistency. It is available in nine designs.
