11 month old not sleeping

We have a 11 month old baby girl She hasn’t always been the best sleeper but mainly an early riser Last two weeks she has been awful sleeping Wakes around 1.30/2am every night and whatever we try won’t go back to sleep till 3.30/4 It’s draining to say the least She currently still has no teeth so possibly teething however when she wakes she’s not upset or crying just ready to start the day 🙄 Any ideas feel like we have tried everything One tired mama 😴
