Haha, Mads shows an interest in mine too. I want her to love photography like me so I do try and let her press the button sometimes. ;)
It's too sweet to be naughty!! I let Kitty play with mine too - I figure if I show her how it works that might satisfy her curiousity enough that she doesn't then try to play with it when I'm not around - so far she's showing every sign of being another photographer!
So sweet! You can't really be angry when they just want to be like you :)
