Hi there!
Looking at your routine, I was thinking that her first A is a bit long if she's waking before 6 am so you could try a slightly short A. Perhaps try putting her down closer to 9 am.
She's napping well so I'm hesitant to mess with it too much but at a certain point, too much day time sleep will rob night time sleep. So you could try capping a nap to see how she does. I think most moms start to cap the am nap. Or you could try a slightly later bt to see if she sleeps in later. This assumes that all she needs is 11 hrs at night. If she needs more than 11 hrs, then this second option will probably backfire in the long run.
I'm not sure where you are located but is the sun rising early? Do you have black out blinds? The sun light can cause early wake ups as will birds, etc. if you don't have black out blinds, I would recommend them along with some white noise to drown out some early morning noise.
