hi,
possible that now separation anxiety has started to kick in on top of all your hard work. since she's almost a year i'd probably try walk in/walk out along with what you're doing. soothe her, then tell her good night & leave the room. if (when!) she cries, immediately return & soothe her again. repeat.... a lot... i know the first few days i had to do it with luke i was doing it close to 45 minutes at a time!
but after a few days of that it got much better.
