Try taking her sleeping pouch and sticking it in your shirt right after she's gone to sleep for the day. It's dark and warm in there so she should hopefully settle down and get used to sleeping there, especially if you do it when she's tired. Mine aren't bra bonded yet but I stick them in there sometimes and they seem ok with it, one's a bit of a nipper and both will nibble occassionally but no one's really deterred me from sticking them in there yet. They seem more focused on hands when it comes to their nibbling/nipping for whatever reason.
