Our 2, nearly 3 year old has been self settling for bed and naps for a long time (around a year) all of a sudden, out of nowhere, she is now calling us back into her bedroom for at-least an hour before she falls asleep. She's not upset or distressed, just calling us back for random reasons, asking for more stories, more hugs etc. I'm responding to her at the moment, but why is this happening and will it stop?! Is this a thing?! She is still in a cot. We have tried cutting naps and nothing seems to make her tired enough to go straight asleep...
