Jack has been insisting that everyone call him "Jackie" since early September. We never really questioned it; we went along with it, since it's not a big deal.
We were talking about the boys' names and Jack was talking about the littles' middle names. We often call them by their first and middle names, Adam David and Mason Samuel.
I asked Jack what his middle name is and he looked at me like I should obviously know this answer and replied, "E."
So, he's not Jackie, he's Jack E.
