She will give up the bottle eventually. My DD wasn't ready until 14 months. We started introducing it at about 12 months, and kept introducing it every 3-4 days for about 2 months before she took it. And honestly, we had almost no problems with the transition. Once she took the sippy, we slowly decreased when she used the bottle. We replaced 1 bottle with a sippy, then 2, then 3, with the nighttime bottle being the last to go. When she would wake up at night, we would give her a sippy, & she would fuss a bit, but it wasn't anything snuggles couldn't fix :) It only took about 2 weeks to get off the nighttime bottles.
Also, you might try different types of sippys... she might prefer one kind to another, like hard spout or soft spout. It might even come down to brand- My DD HATED the Dr. Brown's sippy, but LOVES the Gerber sippy- and they are both soft spout. You just have to find what works for her.
Good luck! HTH.
