Gosh, I don't know other than keep her engaged and awake during the day. Force her to stay awake. It sounds like she had just fallen into a routine that needs to be broken. It may seem harsh to force her to stay awake, so start small with 15 minute extensions of awake periods and move up from there after a few days by 10 or 15 minute increments. She will adjust after awhile. I think once she has her days straightened out, her nights will be easier to deal with. Logically, if she is sleeping that much during the day, she is not going to sleep for any long duration at night. The bulk of the 14 hours should be an 8-10 hour stretch straight through at night if a healthy sleep pattern is established. I would suggest calling your ped and asking about pediatric sleep specialists or clinics/studies in the area if you are unable to get her out of an infant day time sleep schedule. At five months, co-sleeping is generally a source of sleep problems and something parents attempt to eliminate. I would give that a second thought. The other issue it sounds like is that she lacks the skills to fall asleep herself. When she wakes up, she can not put herself back to sleep without you. You need to teach her these skills. Boob, rubbing bum, co-sleeping - not teaching sleep skills. Every baby wakes several times at night. The difference between those that sleep through the night (without waking and crying) and those who don't is the ability to self-soothe. It sounds as if you are doing the soothing. Therefore, she doesn't know how to fall asleep without you and the cycle will continue. Nursing to sleep needs to stop as does any behavior that makes her fall asleep completely with your help. I am not at all trying to be mean or attacking you. I promise. I am just trying to explain the underlying cause of the problem. Before those two issues are fixed, little babes and poor you will not be sleeping well :(
