You poor thing, must be hard getting things done with bubs attached.
Is there any way you could get her to sleep in the sling and then put her in the cot, maybe try having one of your shirts or something in there that smells like you?
She might also like the noises etc when your moving round doing things, so maybe some background music in her room?

Not sure as i never had this but i hope someone has some great advice for you.

GL i'm sure she will sort herself out for you.
