Ana Maria

My friend Natalia posted this picture of Ana Maria on her facebook from her son Santiago's 2nd birthday party and we both thought it was so cute! Lately, she has her fingers in her mouth a lot so this is a very typical picture of her! Natalia caught her in action, at least it wasn't in the nose like it's been lately also! How do you break these habits?? I need advice!
She is still my sweet, beautiful girl!!
