I've never had a bad vacation at any Disney resort (except the one time I got a smoking room instead of non smoking and the resort was fully booked, but that's a different story), so whichever resort you pick you will have a good time.
I would consider which parks you plan to spend the most time in and try to stay in a resort convenient to those parks. Although Disney transport is great, if you plan to spend a lot of time in the MK, you can't beat the convenience of the monorail resorts. You can leave your daughter in her stroller and just roll her on board. I have also seen people roll strollers on board the boat to Wilderness Lodge. However, if you are staying at a resort where you have to use a bus, you have to take your daughter out of the stroller, and carry her and the stroller. That can be a hassle sometimes, especially if you decide to go to a park while your husband is in meetings.
If you are staying in a monorail resort, they are all great, but have different themes. I have heard that the renovated rooms at the Contemporary aren't as toddler friendly as the Grand Floridian or Polynesian. Wilderness Lodge is fairly toddler friendly as well (so long as you keep her away from the water feature in the lobby).
If you want to spend more time at Epcot and MGM, the Epcot resorts are great. In fact, you could book a studio in either the Beach Club Villas or the Boardwalk Villas, and have the added convenience of a kitchenette. I like the studios for two adults and a small child because of the kitchenette and the sofa for sitting. I don't recommend them for more than two adults because I don't find sleeping on a sofa bed comfortable. There are also Villas at Wilderness Lodge with the same layout.
