Jen, maybe try putting a shirt or pj's that you've been wearing with her for your smell?? Also, is the cot in your room or her own room? Not sure if you mentioned that. I used to have Oskar sleep with me at times, but got too scared of him falling out and couldn't sleep properly, so I started to put him in his cot during the day for sleeps and now his cot is next to my side of the bed in our room and that's where he'll be until I can bear for him to be on his little lonesome...lol. I hope something works for you.
