I ended up trying to leave the room a bit last night, and it was semi-successful, as she would be ok for a while playing and singing, then would remember that I wasn't there and cry again. I'd talk to her from outside the door for a bit, then go in and tell her that I would sit on the floor for a minute and then I was going to go out the door again. I'm pretty sure I was outside the room when she fell asleep, and she didn't wake up until 4:30 this morning, but then she took til after 5 to fall back to sleep, was crying again at 6:10, and then up for the day at 6:30. Hoping I can continue progressing with the wi/wo again tonight, but her SA is definitely still in full swing. I had to hold her to fall asleep for nap again today, which means she will be up crying after an hour 10 on the dot. DH put her down for nap yesterday because I wasn't home and she fell asleep on her own instantly and slept 1.5 hrs. She still woke up from that crying for me though. Any idea on how long this SA phase normally lasts? It's easily going on 2 months now.
