I feel your pain hun! It takes a while to get those sleep cycles regulated. The best thing you and your baby can do is get out in the early morning sun without sunglasses. The early morning light will help her start to regulate her production of melatonin and seratonin in her brain. These hormones help regulate her circadian rythmns, and yours. Try to get at least 20 minutes minimum of morning sun.
Do you have her sleep in the room with you? If not, I would recommend this- especially till her sleep cycles are more regulated. You can just use a play yard, or a bed called a "side sleeper". It's a special mini crib that butts up to your side of the bed so you have easy access to her all night and don't have to get out of bed to feed her. Sleeping with or near her with also help her regulate her sleep rythmns. She was in you for 9+ months depending on your limbic system to help regulate hers. She still needs you as she's developing. =D
A great book to check out- healthy sleep habits, happy child.
Best of luck and if you can't sleep when she sleeps- at least lay down and practice some relaxation techniques. Warm blankets on my feet work for me. Also- the body naturally relaxes when there is about a 5" change in temperature. That's why we get drowsy so quick in the rising heat of summer- The change in temperature signals our brain that it's time to rest.
*I know swaddling is super popular- but I never swaddled either of my girls. I did what I mentioned above and their sleep schedules have been solid. The morning sun is incredibly important. When the girls had a difficult time unwinding to sleep for whatever reasons- wrap your little one up in a warm (not hot) blanket, and gently rock her in your arms. It is baby cryptonite! =D
We are natural creatures, and we depend on nature to help us regulate our bodies.
