Counting (on) cousins

I have two siblings, and neither has any children, nor is showing signs of having children any time soon. My husband has two siblings, same deal. So how will Isaac get any cousins his age? I don't wish premature parenthood on anyone -- it's challenging enough when you planned it -- but I find myself dropping little hints. Hints like "Why don't you have a baby? Soon."

See, I was counting on Isaac having cousins close in age, but if everyone waits until after he's three years old, it will be too late.

I loved growing up with cousins my age. We were as close as siblings, minus the rivalry. When I was a kid I used to have a good number of cousins -- I think 11 -- but then there was a baby boom among my mother's siblings and now I have 18. Or are there 19? Wait, maybe 20. This is turning out to be a side benefit to having an abundance of cousins: I can count them. Literally; when I'm having trouble falling asleep I count them like counting sheep. I try to count them in reverse chronological birth order, but by the time I count four or five I'm confused, and then I'm asleep.
