She hides her pizza

Soleil is 2 now and she is smarter by the minute...Saturday we got a very good pizza and I told her that if she wanted to eat ice cream she needed to eat all her pizza. I go do something and come back 5 minutes later and this is what I found: She hid her pizza pieces under her plate. I asked her 7 year old sister if she had done it and she said. "No, I just watched her do it". It was too funny and very surprising. A little kid that small and that smart or should I say...So mischievous. I am in trouble.
