My Wee Friend™ is an exciting, yet simple and effective way to potty train. By delivering a fun instant reward, your child will be motivated to make it happen again. My Wee Friend™ is a black sticker that sticks onto the bottom of most flat-bottomed potties. When your child wees into the potty a happy smiley fun face appears 'magically', to instantly reward your child for their efforts. The smiley face lasts long enough for your child to stand up from the potty and see the smiley face, before fading to black, ready for the next time. Developed by a mother of six and grandmother of seven, My Wee Friend™ has been tried and tested and really works! The stickers are available singly and will last for up to 12 weeks. The potty can be cleaned as normal. Please note you will need a flat-bottomed potty.
