S.T.
huge middle ground between CIO and your husband sleeping on the floor. resign yourself to a week or so of interrupted sleep and defeat this problem once and for all. go to him when he wakes, but do not talk, pick him up, or interact with him in any way but to sit quietly with him and rub his back or arm. if he climbs out of bed or into your lap, quietly lay him down again. over and over. when he's quiet, kiss him and leave. repeat until you're ready to gouge your own eyeballs out. it will take many repetitions, but once he understands that you are there for him but you are NOT going to sleep with him or get him up, he will start going back to sleep on his own.
