I'll have to tend to disagree with you there. Most children do not have the attention span, you are right, but it all boils down to the parents. All childrens attention span is not off and some can even take in good info as early as 3 or 4. This can set the habit for later. Will they learn alot? Probably not, but they will learn Disipline, Self Disipline and confidence. Which are all needed for later in training and life. Just my .02
