11 month old sleeping habits

Mariah

Need ideas on how I should be putting my daughter to sleep for naps and bedtime. Usually bed time is 8 pm and I feed her a bottle and/or walk her around bounce her around/ pat her butt, etc. But she has always woken up between 2-4 am and I change her and give her a bottle and repeat the process. Now she sometimes gets up, i do the routine and she still wants to stay up for at least 2 hours before I can start the routine over....For one whole week [a couple weeks ago] She went to bed at 8 pm and didn't wake up till 5 am or 6 am and we did nothing different and then BAM were back to square one. So I guess its time to change something, I just feel at a loss....
