First, I know you say you set up a routine, and without seeing it, I can only tell you what I did. I believe every child is unique, so I will only tell you about my experience. Also, Supernanny does have some good tips, but at 14 months I would not follow the routine she uses, at least not most of it. It is important that you set up a routine that works for you and stick to it, though. Right now, the routine that works is with a bottle. You need to be comforting in your change of a routine. When my daughter was about your daughter's age, I started our bedtime routine by putting on pajamas, brushing teeth, reading a book, and then singing a couple of songs. I made sure to tell her what we were doing every step of the way. It is important to let her know what is coming next. For example, I would say, "It's almost bedtime, so let's go brush our teeth and then we will put on our pajamas." I let her hold the toothbrush and did not put toothpaste on it. Then I would say, "We finished brushing our teeth, so now it is time to put on our pajamas for bedtime." Continue saying what is coming next each step of the way. Then, we would sit in the rocking chair and sing a couple of songs. After that, I would tell her that it is bedtime and she is a big girl and needs to go to sleep. I would put her in her crib and I would sit in the room near her and I would read a book of my own. I would tell her that I will stay in the room with her if she could be a big girl and I would have to leave if she cried. And I followed through. If she started to cry, I left the room. I would leave for 5 minutes. Then I would go back in and console her, without taking her out of bed, and tell her that I would like to read in the room with her. If she could calm down, I would sit and read, but if she started to cry, I would leave again. I increased the amount of time I was gone each time I left, too. (First, 5 minutes, then 7 minutes, then 10, etc.) After a couple of nights, she understood the routine and I had NO crying. I slowly, over time, stopped reading in her room, and only needed to put her into her bed after reading to her and let her read books on her own. It is really important that you prepare her for whatever is coming next. It is also important that you be near her, at least initially. I would never take away the comfort of mommy AND the bottle at the same time. Everything that is happening at this age is new and unexpected. Imagine how scary things are to you when you are thrown into a new environment and no one tells you what is happening next and then on top of that, they take away the only things you are familiar with. I would probably scream, too! Oh, and it is also important that you remain calm, because they can tell when you are upset, too.
Good luck and let me know if I can help with anything else.
