My ds is 6 and I'm concerned about how much he worries and stresses about things. He will focus on a comment made in passing and literally worry himself sick about it. He also suffers with nightmares.
An example of this is about a year ago a fox came up to our front window, put it's paws on our window sill and looked into our lounge. My ds freeked out and still to this day goes on about the fox. If we are out and he see's a fox he will also freak.
Another example is that I was telling my dd (11) to be vigilant earlier as there have been reports of a man in a car approaching children in our area. Tonight after being put to bed my ds has come downstairs crying saying he is frightened of the naughty man.
I am concerned that he is worrying about things too much and causing himself unneccesary stress and sleepless nights.
