First baby after adoption.

I'm 31.3 weeks and the due date is closing in. I already love this little boy but I'm getting so nervous. Almost two years ago (my c section is scheduled on my first sons birthday!), I put my little man Aiden up for adoption to my foster parents. I'm still very close with him, see him ask the time, and even lived with him up until october 3rd of this year when I turned 18. He's raised to know that she is mommy, but I gave him life, which I totally love and appreciate.

I'm starting to get worried though if it well be different bonding with this new little addition, who I am keeping. He will be close with his biological half brother, that I know, but has anyone been in a similar situation? I love him to bits already, but I worry when he comes out and looks and sounds and acts different than my other boy, I'll go blank minded! Not in a bad way, but, all my parenting prep will fall right out of my head. How did any of you feel having babies you were keeping after having put a baby up for adoption? was bonding harder since it want an opportunity before?
