Toddler concerns

Hi,

I am having a very, very difficult time with my 2 1/2 year old son.  I know everybody is telling me he is just a little boy, but I am having the worst time with him.

We had a catholic wedding we were invited to, his father was best man.  I brought books, crayons, coloring books, puzzles, light up sticks, cards and his grandparents were there.  He kept yelling. moving all which ways,  throwing things.  My brothers and father have ADD.  I know there is somthing wrong because all the other little boys his age were there and they had their moments, but they weren't so hard.  He is always moving.  He doesn't do puzzles sitting down he has to stand up.  I am struggling with this, please help.

Thanks
