Chelsea slept in her crate in my room till she was spay. Came home with an E-collar too big to fit in the crate, put her on the bed and no problems since unless she is sick(tummy probs). She never cried or made a fuss in her crate and would sleep for hours.
Vivian was a crate girl for only about 3-4 months. Same thing, crate next to bed, but would get me up at least once a night or cry. At about 4-5 months, just gave up one night, put her on the bed and no problems except once (on the bed). Play with her trying to tire out and make her go out to potty just before bed, now in morning, she will use the dog door if she needs to go out before I have her go.
I think they are individual just like others have posted.
