My dd started this 6months after going into her big bed. First 6 months were fine, then the day sleeps stopped and then she wouldnt go to bed, did our heads in and df and I kept snapping at each other. Sitting on her bed to settle didnt work as everytime we moved she jumped up and thought we were leaving. Letting her cry it out didnt work as it would wake dd2.

What worked for us was putting a chair in her room and sitting there watching her till she slept, no talking, just picking her up, putting her back to bed with a kiss if she got up. Slowly I moved the chair into the hallway, then further down until I was in the lounge, I did it over a number of nights. We couldnt see her in the lounge but she was happy knowing we were on the chair 'watching her'. Eventually I moved the chair next to the lounge and then got to finally sit on the lounge while she settled herself down. I think it took about 10 days for the whole process but after a month of hysterical bedtimes it was worth it. I don't know what caused it but I put it down to seperation anxiety even though she had never expressed any seperation anxiety before.

Good luck hun, it really takes it out of you
