Hidden chicken

Today, when the boys woke up from their afternoon nap, I was standing over Jack's crib talking to him. Suddenly this piece of pinkish stuff flew at me from out of nowhere. I picked it up thinking it might be something out of his mouth caused by his molars coming through. It was a piece of chicken. It wasn't wet so I guess it didn't come out of his mouth. I think he must have been holding it in his hand, although I did wipe their hands before nap. I can't believe he held onto it and kept it hidden for all that time. They had napped for over 2 hours.
