My little man is 14 months old. I have been trying to get him to hold up one finger since before his birthday. Well, he just wasn't getting it. He would just look at me with a blank expression on his face and there was never any sign that he was taking in what I was saying. Yeah right he knew the whole time. Just the other night while bathing in the sink...he busts out the one finger move. I ran to get the camera and told him to do it again. Like a pro! He was just fooling me the whole time I know it! They are just so smart and they listen and take in everything you do and say. I am just wondering what else he knows in the little mind of his... Or should I say baby genius mind! :-) So much love!
