They wouldn't do anything for pre-schoolers. The show's demographic is 6-11 and 9-14 (i.e., kids, pre-teens, and tweens) Pre-schoolers probably watch it, but their not in the key demographics (which are rocketing to record levels, I may add; good ratings means there's no need to change anything to increase them)
