Update: knowing the journey to adoption is a long one, dh and I started the discussion at dinner the other night. He wants the boys to be 18-(at most) 24 months apart, so we would have to get started soon. We know we want to adopt an infant.
As we were having this discussion, I felt comfortable and decided that I'll call a local agency I am connected with through work just to ask about time and money, etc. so we know what we are getting into. But the more I think about it, the more I just dread the whole situation.
1) we are hoping to move in a few years to a city where the cost of childcare would be completely prohibitive of having another child. This move is something we both want and have been discussing for a long time (I even recently interviewed for a job there and we were going to just pack up and move) and I know we will be kissing it goodbye until one kid is at least in kindergarten if we move forward with adopting. I really don't want to do that.
2) I truly have a heart for adoption and my adopted cousin is one of my very closest relationships (which is why I want to offer my child the same opportunity to share such a bond), but I cringe when I think of trying to chase 2 kids around. I feel like it takes a rockstar to have more than one child and I just can't imagine how exhausting it must be at the end of the day with two small children. Though I know this part will get better over time, my house is already a wreck with one kid that doesn't even walk yet. How on earth will I manage TWO?!
3) this has been touched on before, but I love my son so intensely that it makes me sad to think that he will have to share me. He will still be small and suddenly my attention will be on this baby that came from nowhere. We will have time to discuss a baby with him, but we could be with a mom from early pregnancy or (like was the case with my cousin), the agency could just call one day and say, "we've got a baby that would be a good match. Do you want him? ...yes? Great! Come pick him up!" and then my son comes home from daycare and this "baby" we have been talking about is just there. Lol. I don't want him to feel ignored or unloved because my attention is suddenly diverted.
4) and then my mind goes back to travel and fun again. We can take him anywhere and do so many things (we can take a friend along when he is older, if he wants) if we aren't paying for the day-to-day expenses of two. What fantastic experiences he could have! Why rob him of that to avoid the POSSIBILITY of "only-child syndrome"?
5) and then the dynamics of one adopted and one bio child. Will it make any difference to them? It obviously won't to us, but I worry about those teenage years where kids can be so cruel to each other. "You weren't enough for mom and dad" and "your parents didn't even want you!" It's different, I think, with more than 2 kids, but we would definitely only have one of each. How does that work out?
6) and then I think about how he might be lonely and how adorable it would be to watch him with a sibling. Watching them play outside or build towers together. And argue. And love one another.
It gives me anxiety thinking about it because I can't afford to just take my sweet time making up my mind with adoption being such a drawn-out process. Obviously this is a conversation dh and I will continue to have, but I'd love some thoughts/input from others about my concerns in the meantime. It gives me things to think about.
Thanks for all the responses so far!!! You guys have been great!
