Bubble

I want to put my son in a bubble and protect him from the world. Now that he is off at day camp ( a 40 minute bus ride away) and going into second grade, I worry constantly. Not only about the usual stuff...will he make friends, will he get physically hurt etc... No, I worry about the other stuff. The loss of innocence. When will he discover there is no tooth fairy? When will an older child on the bus tell him there really is no Santa Claus? When will he learn that not everyone is looking out for his best interest? When will he discover lying and cheating? He is so desperate to grow up and all I want to do is scream 'It isn't that great'. How do I protect him from getting hurt? Is it possible to put him in a bubble, feed him through a straw and only let him watch Sesame Street? Would that really be considered child abuse? And how big would this bubble have to be? Right now, even though he logically knows that Mickey and Minnie Mouse have people inside those costumes, he still wants their autographs. This time goes by so quickly. I think I will go buy the plastic and start building today.
