Well dh agreed (sort of) that we should add the pad to the bed. I told him I wanted to be able to sleep in our room like we sleep in the spare room. So we chatted about what is different in the 2 rooms. The spare is darker (I need to put drapes on the bathroom window, which he doesn't want but I am going to do anyway-it has a pocket door and makes too much noise when opened during night time potty trips). The spare room has a bit noisier fan (gotta figure out a white noise machine for him). and the spare room has a softer bed (aha, mattress pad!)
I actually think that one of the main reasons we sleep better in the spare room is also because the bed is actually 2 twins covered with a memory foam pad as well as a 'feather bed' topper. But the 2 twins, in conjunction with the memory foam, keeps the other persons motion transfer to a minimum.
So Ruth, is it that you wake up and then can't fall back asleep, or that you have trouble falling asleep in the first place? Do you sleep better when you are in the bed by yourself? Maybe it is his sleep that is the issue?
