All stereotypes aside, I think there's a tendency to put a negative spin on only children- a friend of mine even said, "How sad!" when I told her I wouldn't mind if Miles was our only baby. I do know families with only children who are perfectly happy that way (and they're not just on TV, as a couple people have suggested to me).
My own history may have a lot to do with it. I have three siblings, and a lot of times growing up I felt crowded or like I was fighting for attention from my parents (I'm not saying I wish I didn't have siblings because I love them all to death, but as a child it was a source of angst). Once Parker and I decided we would start trying to have a baby, it wasn't all easy breezy. There were many months when I longed with my whole being to see two lines on the pregnancy test but was disappointed. I finally got to the point where I realized that month wasn't my time (I had a few of these realizations after some good long cries). We dealt with losses, too. So, when Miles was born, I felt like my prayers had been answered. I still feel that way.
Part of me is also scared. I've seen friends go from one kid to two kids (and some even to three!) and it seems like the level of crazy goes up by...a lot. Miles is a very small amount of crazy. I like that. Some of my other worries come from concerns about finances. If Miles wants to go to an Ivy League school and he has the grades to get him there, I want to be able to help send him- I don't think that's an unreasonable concern (and, again, has a lot to do with my own experiences).
I'd love to hear from the mamas out there. If you're the parent of an only child, how did you come to your decision?
