If you have to have your Husband sleep in on the floor in her room a couple of nights. Put a night light in her room. Leave music playing. Buy her a special bed time toy that she can only have if she stays in her bed. After a couple of nights your husband should be able to get up and go to bed when she falls asleep. When I did babysitting when I was a 13 I had a baby that I watched that wouldn't sleep in his crib. I went and used my babysitting money and bought a night light and radio and put it in his room. Then when it was time to put him down for bed I would put a blanket and pillow on the floor and lay by his crib. After a few times of doing this he started sleeping in his crib on his own and I got a raise in pay from his parents for working miracles........
