I found it!

Abby likes to carry extremely tiny toys around with her all of the time. It's pretty amazing that she can even go to sleep with one in her hand and wake up with it the next morning. She had one with her over dinner last week and at one point I asked her where it was. She didn't know. So Adam and I have our phone flashlights out, looking around the booth, under the table, anywhere we could think to look. After a few minutes of us looking I said, "what do you have in your hand, Abby?" She opened it and there was her toy. She forgot she was holding it. Classic.
