If it helps, I've kind of been on both ends. My mom knew she had a baby, at least, but I'd just been born when I was taken away, and now we're both about the same age. And I gave my kid up when he was a baby and now I'm here raising him. It's rough from either end but it isn't impossible. You may never want to be a mother to him, and he might just be okay with that, so long as he gets to know you. For the way things worked out, my mom is my best friend now. I wouldn't trade it for anything, even if it might have been nice for her to be able to raise me. He'll adjust and so will you, but you've got to handle things at your own pace.
