SO TIRED of my daughters sleeping habits

My daughter is a year and 8 months. I’ve tried everything to get her to bed early or at least sleep at the same time consistently. I’m seriously drained. I feel like motherhood has robbed me of my youth and I’m so damn tired of not getting a good nights sleep. This is giving me major anxiety. I wish she was 15 already

I’ve tried bathing her before bed and a strict nighttime routine. One day she sleeps at 7. The next night could be at 10!! Then the next night at 7:30. Then the next at 11. I’m so exhausted.
