Becoming a surrogate?

So to some I am very young to be thinking about such things. I am 19 and I honestly want to become a surrogate mother. I have a 9 month old and honestly no mater how hard the days can be, I am so thankful I have this baby boy. I want to give that to others as well. It's an amazing thing. Of course I would make sure that it was a good home. Is it weird I wanna be a surrogate?
