Could be He is only 1 1/2 years old, though, but very smart for his age . He loves to play with doors and keys...but if he did do it intentionally, then i better look out...b/c the terrible 2 havent even begun yet!! It is definitly one for the baby book, though. WIsh i had a camera with me when he brought the keys over to the door...priceless
