Trying to sleep train my 8 month old

An

I’m finally sleep training my baby. I haven’t slept well in over 10 months ( including the last 6 weeks of pregnancy). What’s sent me over the edge is for the past 10 days, my baby has been waking up at midnight, wanting to crawl, play, roll, anything but sleep. She’ll stay up for 3 to 4 hours, eventually screaming her way to sleep. 😭

I’m in the mist of putting her to sleep right now. I put her down at 9 pm, an hour early than usual, after a nice bath and song time. Any words of encouragement / wisdom would be greatly appreciated!! Thanks mamas
