I would be that Maryanne. Just don't let them burn down anything or chop anything off. The five and six year old will help, but don't let them tell you they're allowed to do something, if they come to ask they know they aren't allowed to do it. The four five month olds are still in the sleeping eating pooping phase, but they know how to be cute in between. You can totally bribe the eldest two, Timmy and Richie, to help you. The three year olds kind of entertain themselves, just throw food at them occasionally. Now the two year old she is a special case, she's deaf. But she only knows a little sign language. She does better if she's carried around and feels you talking.
It would be US currency, hold on I'll step in just a little farther and get a year at least.
