Lol...I didn't mean for my comment to be taken entirely seriously. That's why I scattered a few smileys throughout and preceded it with, "Honestly I don't think there are any significant reasons why even or odd would be better...." I agree that these silly reasons are nothing to base family size on, but for the sake of answering the original question, all I could come up with was the ease of fair sharing among even-numbered families. You are right though, of course, that odd-numbered families can be just as happy as any even-numbered family, and I was just having some fun with the original question.
I guess I should've added some smileys too!!! I didn't take it seriously, seriously
