The List of all Lists

Wyatt has been writing his Christmas list for a long time.  Mostly it consists of trucks, Lego's, and more trucks.  He just rearranges the order of importance.  When we were finalizing the list to send to Santa, he threw me a doozie:

Can you read that?  That little bitty request at the bottom.  Well, if you can't, it says A BROTHER.  As in, another human.  Oh shit you guys. Can I pee my pants now?

I can't say that this is ENTIRELY a surprise.  He has been asking a decent amount about brothers.  Just a lot of questions really.  Which of his friends have siblings?  How is Aunt Lizzy my sister?  That kind of stuff.  I think it started when Gammy was opening peanuts with Wy. (Do you see how easy that was to blame Gammy? Ha!)  She would open them and ask if it had a brother or not. Wyatt started doing it. Then he started asking if he could have a brother.  I told him maybe someday but definitely not any time soon.  Then we were shopping in the mall and the "All I want for Christmas is a Brother" song came on.  Yeah.  I had never heard of it either.  It was as if a lightbulb went off above Wyatt's head.

"Santa can bring me a brother?"
"Bud, I'm not really sure that Santa can bring you a human.  Santa only deals with toys."
"But maybe I could ask him for one."
Ok, different tactic.  "Are you sure you would want a brother?  That means you would have to share your toys and your Momma."
"Well, maybe I want a big brother.  So, he could have big toys."
That's when I let the conversation drop because I was pretty confident I was not going to win any arguments.  I have a hard time out-smarting him sometimes, especially when he gets something in his head.

So, a few days later when we are writing his list, I am wondering if he is going to bring it up.  We got so close to the end and then he throws out the brother card. And just to clarify, he goes "A REAL big brother.  Not a toy." Then watches to see if I wrote that down.

What to do?  What to do?  Clearly, it is at the bottom of his list.  I am sure once he finds the Power Wheels Fire Truck (that has already been purchased and fought for at ToysRUs!  So Excited!) he will forget all about that pesky brother business.  Can I adopt a big brother somewhere?  Or maybe just borrow one for a day or two?  I am sure that will curb his need for a sibling.  Robot siblings, anyone?
