@ellenw Cinnamon is a pack animal who wants and needs to be with her pack. I don't think she will disturb your daughter working, she just wants to be with her - closing doors and shutting her away from her humans is not good practice.
Put a bed with bones and toys in a corner and let her know she can come and go as she pleases. She'll settle very soon.
If she was too young to have a litter and then lost her pups, she needs her confidence building, not shaking ! Human companionship can do wonders for a Basenji !
