Does age matter?

We were 37 and 46 when our son was placed with us as an infant. We adopted through foster care, and our ages did not matter in the slightest to the social workers who matched us. I think our wait was average given that we wanted a placement where we were likely to be able to adopt. As it turns out, I think it's been a wonderful advantage. We're still young enough to have the energy to keep up with our son. We're financially settled enough that I was able to cut way back on work to have time with him. And I am much more patient than I was when I was younger. Our son can be quite challenging (he's also quite wonderful and I'm crazy about him, but no one would call him an easy kid!) so in my case, I'm a much better mother for him than I would have been in my 20's.
