How many kids? And why?

I figured it would be fun to hear everyone's reasoning on why they want a little family or a big family. 
You can't just say "I've always seen myself having a big family" 
Or "I was raised in this ------" 
Be creative! I'll go first!
I want two kids max. I was in foster homes as a child so I want to become one as well. I would rather help children in need rather than have a bunch of my own. (Nothing against people who want to have a lot of kids I just don't want that many)  But I do want to have at least one of my own. (Which is due in August).
