If she is happy during wake windows then I would say it sounds pretty low sleep needs as well. It's bloody hard for mum though. My oldest did around 11.5/12 hours ago that age and it was tough. But it's very normal as long as they're happy and hitting milestones within the average month indicators. https://www.gosh.nhs.uk/conditions-and-treatments/procedures-and-treatments/sleep-hygiene-children/
My first was exactly like this. He’s 4 now and still only sleeps 7.30-6. He’s fine x
My boy only really has 11 hours a day in total 😂 it’s really not fun as I’d love him to sleep a bit more but if he’s happy then I just try and roll with it!
Sounds like she is just low sleep needs. 11-14 hours is normal
