have you tried just tracking the her sleeps on a spreadsheet or similar? You might see a pattern emerge. Had friends that did this. We never did, but after 3 kids and ~7 years of pretty consistently broken nights from one or other of the kids, I sometimes wish we did. My only other advice would be to take turns with the other parent to give each other a break. Whether it be week on/week off or night on/night off, and may involve someone sleeping in another room to get away from the disruption. I optimistically think a good night's sleep is just around the corner. Cultivating feelings of love and patience is well worth the effort. Having kids that don't sleep well is a special kind of torture, I can see how it would break some people.
