1 year old with no sleep schedule

I know this may make me somewhat of a no so good Mom but my daughter is 12 months and not on a good sleep schedule or routine. And neither am I. Most nights we go to bed around 11pm or later. She wakes up around 10am. I cosleep so it’s hard to put her down before me and for ther to stay sleep. I’ve tried putting her in the pack play to sleep earlier while i stay up for my peace or just some 1:1 time with hubby but she won’t stay sleep for more than 30-1hr. Also she won’t sleep without me putting her to sleep nursing. this is the only way she goes to sleep. I want to continue to nurse at least until 2. And she doesn’t take a bottle. I am really just looking for some advice or tips on how to get this girl to sleep during normal hours. my only concern is if i put her down at 8p she will be up at 6am. seems really early but maybe i’m tripping i prob need to get my butt up anyway. please help! i would really love to hear how to get this girl to sleep on her own. or is too early?
