Anyone choose to have just one child?

Sometimes. My son just turned 4. We tried to adopt again when he was 2, but our FFA stopped their adoptions program 8 months into our wait - after we had been shuffled from SW to SW. We were getting older and my partner decided she didn't want to start the homestudy process over again in order to switch to the county or another FFA. So we just have one. In some ways, it's a good thing. Public schools here are terrible, so educating our son is going to be pricy. That would be a significant stressor if we had two. And the three of us are really pretty companionable. We can take trips and do things with one that we probably couldn't with two. So I'm very happy with our little family. But in a perfect world, I'd love to have two kids. But it is what it is, and I don't dwell on it.
