This is Sara's smile. Can't you see the mischief not only in her eyes but in the way she smiles?! She is 100% trouble and I think her little smile totally gives it away! She either smile with tight little lips biting her bottom lip and showing off those cute tiny teeth. Or she is taking it way over the top. I usually get this second smile if I ask her to smile. Her eyes open wide, she grins ear to ear, shows as many teeth as possible and then adds a bit of attitude. This is Sara!
