A few days ago, we found a small "cat" finger puppet in our family room. No one remembered it or had any idea where it had come from.
After thinking about it for awhile, I realized I had recently seen Lily "at work" behind our puppet theater, constructed by my parents for DD when she was considerably younger. The puppet theater does not get a lot of use these days, and I had forgotten about the basket of finger puppets which sits on the floor behind it.
Sure enough, Lily must have found it in that basket.
To verify that this is the way it actually happened, I staged a small "reenactment". I planted the finger puppet back in the basket and plunked Lily down beside the puppet theatre. And just like clockwork, she dug through the basket and pulled out the cat, leaving the lamb, the bird, and other small animals for another day.
"Dis one looks like me, Mom!" I could almost hear her say.
