Just a thought Em, if you try co-sleeping, she might be happy just to have you near and not demand the bottle... Could be a compromise. Is she in the same room with you or her own?
She's learnign to crawl, isn't she? Teething? All these sorts of things make them more wakeful. Plus separation anxiety at this age. It is really hard and can last a while unfortunately. Hope you get some better nights soon.
