15 month old wakes up middle of the night and awake for 2-3 hours

We went through this for months and what finally worked is night weaning. Nurse her to sleep for bedtime then no milk until morning. We also got her a floor bed so that we can at least lay down next to her if she wont sleep alone.

We have been going through this for a couple of months - not every night but frequently enough that it’s TERRIBLE. No advice, just sending sleepy thoughts!

Mine went through that for a couple weeks but is moving past it now. I think this is a common one: https://takingcarababies.com/14-15-month-sleep-regression
