2 year old sleeping earlier

Did anyone else’s 2 year old start falling asleep earlier? She hasn’t really wanted to take naps lately (which I normally do around 12 or 1) and we’ve also been out a lot so sometimes she’ll just fall asleep in the car for 20 minutes. But the past 2 days I’ve had to leave the house with her to run errands & she falls asleep before 11. Like I just went to the store real quick with her and on the way back she fell asleep & I was able to get her out of the car seat and into her bed and she didn’t wake up? normally she jumps right up and doesn’t wanna go back to sleep. Also normally she has solid poops but lately it’s been a lot of mushy diapers. When she’s up she’s playing all day so I haven’t seen a change in her behavior.
