I am Thinking 4 should be awesome!

So Jon and I have decided that a sibling of three would be awesome from the ages of 2-12. So add them to June and then I would have four children in my home, five total. I would honestly like 12 at some point, not all at once but over time. After the kids are older or in college we plan on adopting 1-2 16&17 year old at time just to give them somewhere to come home for holidays, send letters, get gift packages from, just to call home. Then you know stop having kids around 55 or 60 so I figure I can have at least 12 children by then. I want to be the family that has to rent space for holiday dinners.
