"That kid is not my son."

I need a baby. Not my own and not necessarily forever, just for a little while. See, this is my problem. Jack is three now. You know--the terrible twos plus one. Added to those complications is the fact that he's an only child. I have mixed feelings about this. On one hand, it's awesome! I can take a nap everyday if I want to, I have a little buddy to hang out with, we're not in the depths of poverty..it's a good life. On the other hand--he doesn't have to share, he has my almost constant undivided attention (unless I'm blogging and neglecting him!). He doesn't do a blessed thing he doesn't want to do. The child doesn't dress himself or brush his own teeth. Spoiled friggin' rotten. Exhibit A. Tumbling class. We signed him up for tumbling hoping it would help him gain the necessary social skills and headstart to exercise that he needs to keep him from turning out like either of us in any way at all. This is Jack in tumbling class:Yes, that is a darling picture of 6 eager toddlers trying to do a straight jump. Then there's Jack, lying on the floor because he's "too tired to jump right now." Fan-friggin-tastic. My kid is "that kid." The one who doesn't participate because he's "too tired." The one who looks at his perky (and extremely patient might I add!) tumbling teacher like she's just asked him to shoot up while downing a fifth without taking a breath. I'm pretty convinced all of this stems from the fact that he is without siblings. Maybe I'm just giving into the pressure. All of the people (Scott mostly) asking me if we're EVER going to have another baby since clearly our reproductive issues are the business of others who just want the benefit of HOLDING a baby without giving birth to one. I've toyed with the idea that perhaps having a baby at this point would be silly--by the time a baby is old enough to play with Jack (read: take his toys) he will be in school and will have friends to keep him busy. But the fact remains--something has to be done right now. So I think I need to rent a sibling. Is there some sort of an organization that can help me out with this? I don't want one for keeps (and I'd prefer one who sleeps through the night) this would be a temporary situation, just until I can produce on of my own. (if that ends up not working out, could we work out a lease with an option to buy?) I realize this is somewhat unorthadox, but I'm getting desperate. Rest assured, the child you loan me will be fed, clothed, housed, yelled at and neglected for blogging purposes as if he/she were my own. We have a ridiculous amount of toys that he/she will be able to play with if they can be wrangled from Jack's death-grip. Really, it's win/win. Jack gets a sibling and (hopefully) stops being the spoiled rotten monkey we've come to know and love and you can take that trip to the Bahamas that you've always wanted. Any takers?
