Okay. Here's an update.
Yesterday we did her nap a bit earlier 12:45 and she slept through for 2 hours and 45 minutes.
I put her to bed earlier around 7, but she didn't go down easily at all. It took me an hour to get her down which seems to be a trend the past week. Not sure if it's related to her being OT or not.
She slept the whole night, but woke up at 4 and my husband gave her a bottle and she went back down until 6.
Today she went down for her afternoon nap at 12:30 and I had to wake her up at 3. I'll try putting her down earlier again around 7 and see what happens.
The screaming wen we leave thing is new. She doesn't seem to like us leaving the room which I know I common, but none of the methods seem to work either. PUPD doesn't work, she gets really upset every time we leave. My voice seem to calm her, but again, the moment I leave she's screams. We pat her and rub her back , but again the moment she hears us leaving, it's over! I'm not sure what to do.
