A very frequent bad habit in children (and adults too) is to sit down to play, write or paint arching the back.
Kiddy Up is an invention created to solve that problem. It is a kind of belt that is placed on the back at the waist with two elastic bands that are hooked on the legs.
Approved by child therapists, it helps correct bad postural habits since childhood to avoid future back problems in adulthood.
It costs $ 30 and also comes with two longer rubber bands that are useful for stretching exercises, very useful for both children and parents.
