I can only concur vividly with your perception. In my daily work I see an alarming increase in children with stress related symptoms. Not least headache and pain from the stomach and intestines. I see migraine with preschool kids as young as three to five years old. There is physically nothing wrong with them. They are simply in pain. Typically, during the long Swedish summer holiday, they feel much better.
I believe our stoneage brains are not fit to handle all the constant input we are flooded with daily from very young age. Two year old kids with their faces planted at a Ipad. Its just not what we are evolutionary fitted for.
