You're not alone. My baby's only 5-mo-old, but already she doesn't have a regular bedtime! Sometimes she falls alseep early (around 9), other times, no matter what I do, she wants to stay awake (the latest was 11:15). I can usually get her to sleep in a mei tai if she's resisting sleep, but I can only imagine how hard bedtime will be when she's a toddler (and the mt's not a viable option)! My husband and I are night owls, so she comes by it honestly. I teach college classes (online right now, a combo of online and evening when she's older), so I'm able to sleep in late. When she has to get up early for school in future years, it will be a hard transition for her, I know.
