You might consider the option of putting a baby playpen (playard) upstairs in the bedroom so she can sleep upstairs in your room and you can both sleep in bed. She will probably love it and you will both get the sleep you especially need right now. Basically you line the bottom with towels or blankets or even specially fitted playpen sheets. If she wets any spot overnight, usually they will move away from it. This means you will be doing a load of doggy laundry every couple of days but it is no different than a baby, just a little urine, and the urinary tract is a sterile tract. You could even get her her own laundry basket or bag. I do not recommend lining the playpen with disposable pads, they are not absorbent enough to ensure her skin is protected. You will need a tip proof water bowl. A secondhand playpen is fine if you can get one at the thrift shop, or there is a good chance one of your friends will have one in the attic or basement they no longer need. However, if you decide to buy one, there it no need to spend a lot, a cheap one will work just as well as the fancy ones. I think they are so heavily regulated, they are all very sturdy and durable, even the inexpensive ones. If you do not have much space upstairs in the bedroom, they make a smaller playpen called a side sleeper, they are more expensive but take less space.
If you look at this example of a doggy playpen, what I do in the morning is, I untuck one end of the bedding and simply roll it up (like a sleeping bag) to carry downstairs and put with the laundry. If she doodles, you can either pick up the doodles with toilet paper and flush in your upstairs bathroom, or shake out the bedding in the back yard or over the trash can when you get downstairs, before putting in the laundry hamper. It all works really well. I am suggesting this because when it is morning and you and your wife are dressed in nice clothes to go to work, it keeps you clean if you roll up the bedding instead of kind of grabbing the corners and bunching it up (like we normally do with human bedsheets). If you roll it, you have a nice, neat roll to carry down the stairs and everything stays tidy.
If there is any issue with her dribbling a bit when you carry her downstairs, you may want to wrap her in a towel, you'll figure out what works.
