Toddler waking up

Sa

Hello ladies! So my 22 month old has been waking up like clock work in the middle of the night. She’s not crying out but laughing and playing with her stuffed animals in her crib. She wakes up around the same time and will just play in bed for an hour or a little bit more. Since she’s not mad I’ve been letting her staying in her crib as I don’t want to go in and turn it into a habit. I’m thinking this is normal but wanted to check with you all. Also, is it okay to just let her play?
