Comfort Toy at bed

Coco used to only go to bed with her dummy which was great as I tied it to her outfit and she can't lose it. However over the last two months she's been taking bubby to bed (dolly). She was ok to begin with, but now she seems to throw her out before bed (whilst going to sleep) and then crying for her, and then wakes up and calls for her in the night. It's really driving me nuts and Im wondering what others have done in this situation. She is 20 months tomorrow and Im thinking I'll have to go cold turkey with bubby but that would mean during the day too, and she's soooo attached. What to do?????? Thank you xoxoxo

Thanks Jelive, the only problem with that is that she wakes up during the night and has the same problem.
I just got her to sleep though, without bubby, but with major hysterics. I patted her to sleep in the end (an hour and half after bed time she fell asleep). Pretty nervous if she wakes during the night as I will continue to keep bubby out of the cot. I have decided though that tomorrow I will buy a dolls cot and we will put bubby to bed every time coco goes to bed! (spent alot of time thinking whilst I was patting her to sleep)!!
