I honestly don't know. We visited when Juliana was 4 months old, and she adapted to us really well. She never cried for her foster mom, and she was perfectly comfortable to be with us. She smiled a lot, too!
Then we had to go back home without her (believe me, I know
exactly how you feel right now!). It was another 3 months before we saw her again for the pick-up trip. She greeted us with BIG smiles and giggles, and again she had no trouble adapting to us and letting us be Mommy and Daddy. Was it because she remembered us, or was it because she's a good-natured kid who likes everyone, or could she just "sense" that we were her new family? I guess we'll never know, but any way you look at it, we've been blessed with a very happy baby.
I believe that on some level, Addy will know who you are. Of course she won't be able to think to herself, "Okay, cool, this is my mom," but I think she'll sense it, like an instinct.
The wait is harder for you now, but just keep reminding yourself that it's
temporary! You'll be with her again soon, and in the meantime, keep enjoying the little ones who ARE home with you.
