Hello - So, when our daughter was 9 months, we did CIO with great success and she has slept well ever since. She went down awake, we left the room and she was asleep with no crying in minutes. She's 20 months old now and a few weeks ago, she started waking up during the night and we would pick her up and settle her and she'd go back to sleep. This progressed to us basically holding her all night, every night for a week. We went to the dr and she had a slight ear infection and is starting her 2 year molars. The ear infection is clear now and the molars are settling down, but the inability to fall asleep alone is still there. We've stopped picking her up during the night and only go in and sit on the floor until she goes back to sleep. I know we need to get her to go back to sleep on her own without us there, but I'm not sure how to make that leap. She seems to be having some separation issues as she clings to me all day and has started crying again when I leave her at school (which she hasn't done in months). Any advice would be appreciated! Thank you
