I think a lot of adoptive parents feel the same way about how their children were "meant to be" a part of their family. I have just another example of why Frog was definitely meant to be my son. He came up to me yesterday with a DVD in his hand.
Frog: More? More Chitty Chitty Bang Bang?
Me: You want to watch Chitty Chitty Bang Bang?
Frog: Mmm hmm. singing Chitty bang bang chitty chitty bang bang....chitty chitty bang bang we love you!
