Honey it doesn't sound like youa re doing anything wrong!  In fact, reading what you say it seems to me you are close to family utopia LOL

Some kids are just more highly strung than others, and he is probably a sensitive little soul - and I would say probably wise for his age even though I ahven't met him.

My now 14 year old was very easily stressed, so I just regularly talked about all the good and happy things in our lives, and how fortunate we were, and reminded him that worrying only makes us uptight and doesn't solve anything.  He also needs to understand that things can and do go wrong but that it is part of life and none of us have much power over it.  Tell him that is why kids ahve mummies and daddies - so they can do the worrying if need be.

I agree with what the other lady wrote below - play soothing music and Enya is a lovely choice! 

Above all - RELAX and tell yourself you are a great Mum, and are blessed to ahve such a happy family and loving partner.

 Hello.  I remember those days very well.  It's enough to make your hair fall out. I have two sons, now grown, and one 9-yr. old granddaughter.  One thing that worked with my first son who was just like this was MUSIC (still does).  You might try playing Enya in the background, it is soothing music. And classical soothing Disney music works wonders.   It is important  that you do not ask what you are doing wrong, because the answer is nothing.  If he senses your self doubt, and he will, he will become more hyper than ever.  Do some very deep breathing, and try hard to shine on his acting out.  When he is quiet and focused on anything at any time, praise him in a kind, soft and gentle voice.  A long luke-warm bath with only 2 of his favorite bathtub toys PLUS soft music  and bubbles might help him to destress, too.
