Wade--congratulations on your new family member! I think you need a new family picture, I don't see all your kids in that one!
The thing about large families like that is that they can be a good or a bad thing, many of them run extremely smoothly because everyone knows that they are needed and have a place and responsibilities in the house. I grew up in an area where there were lots of large families, and one thing I can say is that even though the families were large they were usually a whole lot closer then smaller families and they usually spent a lot more time together then smaller families.
Of course it does frequently require older children to take on more responsibilites at a younger age then in smaller families, so they get less of a childhood. But there are worse things then an overdeveloped sense of responsibility.
(and for the record, I have three sisters and a brother, which I don't consider a particularly large family)
