I'm not quite sure if he knows it or not, but our 4 year old son is quite the sweet talker. Not only does he have a way of giving you "the look" along with a dashing smile, he has quite a way with words. I have no idea where he learned this either because nobody around him speaks like this.Usually when I am annoyed (but not always), he'll say, "MumMum, you're beautiful." Then, if he doesn't get the reaction that he wants, he'll follow up with a "MumMum, I love you much. I love you more. And I love you most!"
Granted, he usually uses the same line on me over and over again, but I cannot imagine what he is going to be like when he starts to be interested in girls. The ladies better watch out!
