We had a similar rough spot, but it was around 12mos. What worked for us during the rocky patches is I would wake (or DW would wake me, it's all a bit fuzzy now) and I'd put myself between DD and DW.
DW got a lot more restful sleep, DD seemed to get restful sleep, but I had to pay a little in the bargain.
Would that be an option for you guys? DD only woke a couple times a night at that point, so it wasn't too awful.
