5. They have headaches.
Headaches caused by stress and tension are unusual for children. They are only a little more common in teens. When a child has a headache, it is most likely caused by a minor illness, allergies, problems seeing, or getting too hot or tired. If you notice the child has a headache more than once a month or so, it needs checked by his doctor. Of course, if the headache is severe or lasts for more than a couple of hours, check with the youngster’s caseworker or call his doctor. The point is this. Rule out possible medical causes before considering stress.
