About a month ago, I was happily reporting that Carter was gloriously sleeping through the night. Well, he has recently discovered his feet in the middle of the night and wakes up every morning at around 4 AM to use them as a drumstick on his mattress. It sounds like a car door is shutting over and over outside. He is never fussy or cries. He just wakes up and plays for about 2 hours sometimes off and on and then goes back to sleep. But guess who can't go back to sleep? We haven't been doing anything differently and I don't understand this sudden change in behavior. He also is clawing at his face and forehead in his sleep. He wakes up with a new scratch each day. We just have been telling everyone that he sleeps with a cactus!
