My Wee Friend is a black sticker which sticks on the bottom of most flat bottomed potties. When the child wees in the potty a motif appears, which really encourages your child to succeed! It will fade again ready for next use, but will last long enough for your child to see it and show you. (Make sure you are close at hand, as your child may try to carry the potty and contents to you to show you!)
There are different motifs to choose from.
