5am wakes

Hi! Has anyone successfully overcome the 5am wakes? And if so, what worked? My 10 month old baby girl has been waking at 4.30/5 every morning for the last few weeks. Initially she was a terrible sleeper, then after learning to self soothe, she was fab for a while, sleeping approx 7.30pm-6.30am. Unsure whether this is a regression thats stuck, or if there’s anything else I can do to help her stay asleep a bit longer. As well as me being exhausted, she’s so tired by around 7/8am and needs to go back down for a nap, and naps are now all over the place. I’ve so far tried earlier bedtime, later bedtime, longer wake windows, longer naps, shorter naps… any advice appreciated :)
