Yes I have to agree it seems sad. Just a last thought, do you think she feels lonely in her bed? Could you guys go together and buy her some special bed friends? Dd had a small rag doll when she was young, as she got older she would lose it in the cot so I gave her my bigger pooh bear. As she moved to her big bed we gradually added another bear, small one, then when she was sick she added her small elephant. 3 is our cut off point, big one in 1 arm 2 small ones in the other. On the rare occasion she is sick or having a bad night we add her cuddly dog but after 3 nights it goes back to the shelf. Little cutie gave me one of her bears when dh was on a trip so I wouldnt be lonely, then insisted I keep it.
I really wish we could figure something out for you, meantime I guess you can just make her comfy as possible, put her in nice warm soft pjs and do you have a rug inside the door? Could you put a duller light bulb in her room so it doesnt seem so bright maybe when she is sleeping, I would hate to be sleeping under a bright light.
