My children are blessed with an abundance of cousins. Between both sides of the family, there are 14 first cousins and they are all in the same age range as mine. Since I only had one brother and no cousins growing up, this makes me so happy.
Lots of aunts and uncles... lots of cousins (of all sorts, first cousins, first cousins-once-removed, and second cousins) all of whom we see on a fairly regular basis. It is an embarrassment of riches.
Now, back to the fun.
