Neices and nephews are priceless! All the benefits of your own and then you can take them home when you've had enough.
My wife and I had a baby scare a couple years ago and it got me thinking it might be kinda cool to have one. I had my nephew/godson spend the week with us and it cured me real quick. He's a great kid but it just takes so much energy to constantly entertain a 6 year old.
