Matthew was nicknamed "Peanut" by his mother shortly after birth. How shortly, we're not really sure anymore; within the first few sleep-deprived days is all we remember.
Matthew never did go through that period of sleeping all the time that baby books tell you newborns are supposed to have. Since his first abnormally alert days he's just become more and more active, and at some point his uncle Grant conferred upon him the moniker Savage.
When we returned from Washington, Isaac's internal clock didn't catch up for a while and he spent the first night back up until 11 Central time. He slept in a bit the next morning, but not enough... and ultimately fell asleep between bites of Rachel's homemade spaghetti.
(Since then, he's gone to bed at a reasonable hour AND slept in later than usual. I think it's because Matthew stayed with Grandma for an extra week and isn't here to wake him up in the morning.)
