Little Bed Hog

I have a little 5 year old AndyBoy that seems to think he needs to sleep in my bed.  Wow, calling it my bed is quite a stretch.  Some days I get quite lucky and Andy is only occupying two thirds.  I try to move him over to create a little more space - it is all for not.  Why is that the case?  He is such a little cuddler and when he is not cuddling, WATCH OUT!  He actually gave me a kick to the face the other day and I take hits on a regular basis.  I suppose I need to come up with some sort of incentive to get him to sleep in his own bed.  The challenge - Andy falls asleep with the light on and Jack will not allow that.  I let Andy lay down in my bed while Jack goes to sleep in their room.  I should move the little fella but usually when I lay down I am done and at that point I don't care about the little bed hog.  Besides that I would say a solid 95% of the time I do move him he ends up right back in my bed anyway.  You know, it's a good thing I love that little guy.  He is a sweet boy and such a joy in my life... and sometimes he is a knee in my back or a foot under my shoulder or a hand on my face...
