So for a moment I felt stupid for my lapse. Being the worrier that I am I began to panic that I had forgotten where he came from, and that if I didn't make it part of our daily conversations that he wouldn't feel comfortable about his adoption. (not that I would forget that - I feel it's very important) But then I realized that this is the way I ought to be feeling about my son. The fact that he's adopted shouldn't identify him or his place in our family. And it doesn't.
This child feels as much a part of me and my husband as our biological child is. I think that's the way it should be. He is our child. Momentarily forgetting that he isn't our biological child is a completely natural thing!
And then I felt very much at peace. I think our family is exactly as it should be.
