Maybe you could set up a special playdate for your son? Even just one friend over to celebratewith would be fun for him, I think. Order in pizza or some other food that they like and let them run around for a bit, being boys. Don't stress it. I know as moms we want everything perfect for our kids and succumb easily to the guity feelings, but if for some reason you are not up to a big party, this could be a compromise for you.
Happy Birthday to your kids!
