Please Help Me Sleep?

i just got a 8 wk old kitten yesterday and he took to me very quickly and very hard. he very seldom plays by himself. Most of the time, he's constantly jumping on in my bed to sleep. This normally wouldn't be a problem, but he wakes up to the slightest movement in the bed and thinks its time to play and tried to claw my leg that moving under the covers. I really wouldn't mind him sleeping with me if he would just stay asleep. He would be fine until I start moving. HELP!!
