I too was shocked at how easy calpol was given to children, the mother who used a bottle a month
I also thought most of the evidence was one sided and more opinion than fact.
eloethan I attended an interesting seminar on ADD at the centre for life. The professors opinion was that ADD has always existed but in the past children had outlets which they no longer have and it is society that has changed.
Examples he gave were that we could play out for hours, running, climbing trees, riding our bikes. Older boys could work on the docks or for the local store while still attending school etc. There were technology schools for practical subjects and PE was a regular curiculem activity.
He gave examples of marines, mine workers and a few people in history where being brave, fearless and functioning on little sleep was seen as an asset as opposed to reckless behaviour.
He opined that today our children are sat in a classroom for hours and forced to learn a restricted curriculum, fidgeting or lack of concentration is punished or seen as weakness that needs to be controlled. So much emphasis is on academia and most outlets such as PE or activity subjects are now restricted.
The child that runs around the park for hours is frowned upon and seen as out of control. Parents are afraid to allow their children to go out on all day adventures on their bikes or in the woods. Activities are more sedate and restricted and no one plays out when there is homework to be done.
And our food has far more additives, (including calpol) He believed that society had removed outlets and added conditions, but that ADD has always existed, (just as ASD has,) however we are more aware,
It was a very interesting theory.
