Sweet snarling child of mine

Why does my sweet child like to make snarling mean faces at me when I'm trying to take his picture??? He's always done it, even before he understood what the camera was. Here's is a mean-faced Nicholas at 3 years old...



And look at this little guy...



Recognize that toothless snarl? That was Nicholas when he was only 10 months old. You see, he's always done it. I have tons of snarling child pictures. He likes to be silly but it can be so very frustrating. But then he turns around and gives me the sweetest, most playful looks and my heart just melts (please disregard the pizza on the corners of his mouth and the watermelon dripping off his chin!).....





Sweet child of mine, snarling or not!
