When Kyle and I were dating, we got in quite a bit of babysitting experience together. We have seen what becomes of kids who eat "kid food" on a regular basis. A friend invites them over for dinner and said kid complains that he doesn't like what's being served and can he please have a pb&j sammy instead. We didn't want to grow ungrateful kids like what we had seen. We wanted our kids to be able to eat anything and just be thankful to have food.
This comes much easier for our African children, than our American-born children. Go figure.
