I must tell you that I had the same problem, and my son (he is now 6) STILL does not sleep through the night every night, but he has found a way to sooth himself to sleep without waking me up every five minutes, and he learned way earlier (like at six months-old). Each child is different.
Your baby is now a year old, so breaking the cycle is going to be EXTREMELY difficult. When he/she wasn't able to walk to your room, you could have left your child to find a way to sooth himself/herself. Instead, now you are faced with quite a dilemma.
The best advice I can give you is to stop allowing your child to suck on the bottle...it's time she is broken from it. I started my children on a sippy cup at nine months old, and I NEVER used the bottle as a fall asleep method. Instead of running to her side to comfort her, direct her back to her bed, pat her on the back while you are sitting next to her bed, and move further away each night. Oh, it is going to be heartbreaking for the first few nights. It has to be done, though, for your sanity. Eventually, when your daughter cries, you will have to avoid going to her, so she can find an alternative way to comfort herself. The cries will get shorter and shorter, and eventually, they will stop. It is going to take a number of cried-filled nights, though, just because of the fact she is a lot older than just a few months.
After 6-9 months, it is not an "I need you" cry, it is a cry of being spoiled...I know that no parent likes to hear that, but it is the hard-cold truth.
Been there, done that
