Our son age 3 always asks for this when he bumps himself and finds it a great comfort. Even if it does hurt we tell him Mr Bump will make it better and he forgets all about the pain. Also great for burns as we found out today when he burnt himself. We keep ours in the fridge so it is easily accessible. His playgroup also have one which is where we got the idea from to get one as he kept asking for Mr Bump at home when we didn't have one. We also have one at each set of Granparents houses so he recognises it as a comfort and stability.
