Seriously how do people handle 6 kids?

I have 4, and am totally superhuman! Well my oldest is nearly 9 so he's in school most of the time (except for vacation which began this week), and my 5 year old will be off to school next year. My 2 year old is surprisingly extremely well behaved and easy, and my baby will probably be a handful, but thankfully he isn't walking yet. I was prepared for the big family I always wanted.
