Sleep training toddler

hi everyone

Our toddler is continuously waking up around midnight to 3 AM. I’ve created somewhat of a bad habit by just bringing her into bed with us, rather than trying to get her back down. This happened after countless nights of not being able to get her to go back to bed.

now I’m afraid I’ve created a bad habit, and she now wakes up in the middle of the night expecting to come to bed with us.
