Newlie lays on me a lot. He will start off the night laying on me, then at some point move away, and then come back on top in the morning. Occasionally, he will also try to sit in my lap. I don't mind any of this a bit, but if you do, then you are well within your rights not to allow it. Newlie has been doing this for some years and, during that time, has weighted somewhere between 70-85 pounds so he is no lightweight. It is not uncomfortable for me, other than the pointy elbows, when he lays across my torso, but I do not allow him to sleep across my knees, that smarts!
