Welcome to the forums!! How many hours in total is Coco crated?? I think having someone to come in and take her for a walk, and give her a mid day meal would probably help. It's hard on both you and the pup...you need more sleep, and she needs more time stimulated and exercised. At her age she is going to need less sleep and more time out of the crate.
Is there a doggie day care that she could go to on the days you are needing sleep?
