When we first got our little ones, my husband wasn't comfortable allowing them into the room (he wasn't comfortable with the prospect of them watching during...well...ya know...LOL!!), but when we moved into this particular place, we leave it open until about 4am to let the cold of the AC move into our room from the livingroom.
They've enjoyed the time with us, but don't ever really try to sleep on the bed with us. They started out wanting to lay on the bed, but now I've noticed that they've found their own places they like in the room. For instance, Sunny likes sleeping on the dresser (she likes high places, and it's the highest in the room), and Hobbes likes laying on the floor right in front of the bed (he's a bit of a guard cat, so he likes to be "guarding" the bedroom door).
Every now and then they jump on the bed and lay at my feet, but it's rare anymore.
