5 year old sleep regression

[whydontkidscomewithauserguide]

Hits my 5 year old has always been a great sleeper. She has suddenly started waking every night around the same time, 11pm ish, and can’t get back to sleep. Is this a “thing” at this age?

I'm not sure that it's A Thing as such, just a habit for your child. They go through these phases though. Just keep taking her back to bed and eventually she'll get the message.
