Dahling, if you need it explained, you just won't understand it...
I am being sarcastic (I hope you got it)...but in the lifestyles of the rich and near famous, a second child would (could) mean a second nanny (so a second nanny suite would be needed...ie, another bedroom w/ at least a 3/4 bath attached...I mean can you really hire good help if they have to share a privy?)
Now there is always a solution. Give the nannies bunk beds. :)
