Insert Foot in Mouth

For the past few mornings when I've gotten Jackson out of his crib, I've noticed that the feet of his pajamas were wet. At first, I didn't know what was happening. Then it hit me--he has finally succeeded in getting his feet in his mouth. I just hadn't caught him in the act yet--until yesterday morning. I got him out of the crib and saw that the footies were wet again. I put him on the changing table for a clean diaper and it happened--he started licking his heel! Then he moved on to his right foot and stuck his toes in his mouth! Do you have any idea how difficult it is to change a diaper on a baby that is constantly trying to stick his foot in his mouth? I thought I was going to have to hold his feet down! Is this considered a milestone? Even if it's not, I'm kind of proud. Jackson has been working so hard on getting those feet in his mouth. Practice makes perfect, I suppose!
