I think whatever you do with the crib, you're daughter is going to hate it compared to sleeping in the bed with you and your husband. If you put the mattress on the floor or make the crib a low toddler bed, I'll bet you dollars to donuts she will be out of that crib/toddler bed and into your bed in a flash. If you plan on ever having her sleep in her own bed in the future (it is completely up to you and your husband), I would say this move is a good opportunity to transition her into her crib, set up as a crib with the side all of the way up to keep her in there. The transition to her own bed is going to be difficult (atleast in my experience) with a lot of nights of crying and repeated waking up with crying, but eventually, she should settle into her own bed. It is just a matter of when you want to do it, and the longer you have a kid in the bed with you, the harder it will be to get them out :). They just get too accustomed to having you right there all night. My 10 year old step daughter still sleeps with her mom when she's at her mom's house! I don't know about you, but I definitely want my kids out of my bed by 10!
