I have a 13 month old daughter. At around 11 months she too went through this stage. Here'e what I did...I tried not to give her a bottle. She didn't really need it. I gave her water instead of formula. I tried to just rub her back and get her to sleep without picking her up. I sang low songs and spoke in a whisper. I found that it only made it worse when I picked her up, her seperation anxiety went beserk when I left again. But the good news is she stopped within a month and now sleeps great again. Good Luck.
