A Cry For Help!!!

Tonight my six year old son blew his poor mothers mind.

We were watching the TV show Castle and there was a kissing scene.  It was not a hot and heavy one, but a kiss nonetheless.  Gage proceeded to make an extremely Rated R comment.  I died on the spot and did the only thing my brain could function enough to do.  

I sent him to his room.

My sweet six year old baby whom I have nurtured, coddled and basically sheltered.  How on Earth did he come up with the naughtiness that escaped his mouth?  My baby who still passionately believes in Santa and truly thinks that he will be heading to Hogwarts in a few years time.  

So Keith just looked at me and asked me why I sent him to time-out.  His thoughts were that Gage may not have understood exactly what he said meant, and that he shouldn't be ashamed to talk to us about that stuff.  

I basically became hysterical and on the brink of tears as I squeaked that six is not an OK age for this to be coming up.  Keith headed upstairs to explain to Gage that his statement was not appropriate and that there are better ways to approach the subject.  With every cell in body I wish that Keith had told him to never speak or think of the subject again, but evidently that would be unrealistic.  Psshht.

So I hear Gage and Keith walking down the stairs.  I hear Gage say in his tiny, lispy little voice, "Sorry Dad. I didn't realize what I was saying was inappropriate.  I will find better ways of saying things from now on."

Sob.

My baby is not supposed to be able to say the word inappropriate, let alone know how to properly put it in a sentence.

So here is where my cry for help comes in... what now?  What do I say if he approaches the subject again or makes another comment?  What do I do to let him know that I want him to feel open enough to come to me and what is the proper way to talk about it with a six year old.  I am so utterly lost.
