Ina how nice that your daughter wants to be with her mom when her baby is born. OK, so that is an assumption on my part, not having kids of my own.
my house is 1600 square feet, 4 bedrooms. I have a spare bedroom (the smallest of the bedrooms) and one I use as an office/pantry. It is directly off the kitchen and I have zero cupboard space in the kitchen so I use the closet in the office for kitchen storage. Those rooms are down stairs. My bedroom and craft room are upstairs. There is an odd little room off the side of the craft room I use for my sewing room. Off the back of the craft room is an old fashioned sleeping porch.
