Adopt 2nd Child? Age & Finances vs Single child

I've been thinking about a lot of the same things. I really want C to have a sibling - my brother and I aren't real close now, but we were growing up and as young adults, and I want C to be able to have that. I can't afford two daycare tuitions, and honestly, right now I don't think I could keep up with a second child (I'm a single parent and C is an extremely active 19-month-old). I don't know that I could afford another private adoption, either. I have thought about foster care, maybe when C is a little older, but I worry about the effects of that on C as well, both in terms of behavioral issues as well as if the child left. I don't know that I have advice for you, since I'm struggling with the same things. I think it makes sense to want another child, and I don't think there is anything wrong with your son being the reason for that.
