It's funny, we know a ton of only-child families. Maybe it's a coastal academic thing? So my DD thinks being an only child is quite normal.
Lovemydd, maybe you could talk with her about how China has -- or, had, rather -- their one-child policy. I think that, obviously, there's both good and bad things about, but that sort of captures the whole only-child thing pretty well. For example, you could talk about how some people want a second after the policy is over, but many say they just don't. Furthermore, I think maybe it could help put it into perspective -- after all, if all of China can do it, it must be survivable. It's not the end of the world. (It cause some economic problems for them, I guess, but you get my point.)
