Hi Alisa,
It looks to me like her wake-up is really around 8/8:30 rather than 6/6:30, if she's going back to sleep after that 6am feed.
A bedtime of around 8:30 would make sense, then, but she's not falling asleep until 10? What is happening for that hour and a half?
It also looks to me like she may be in need of a little bump in A time, if she's needing to often be resettled at the 40min mark and is having trouble settling at BT. She's basically got three full naps plus a CN, which is probably on the verge of too much. As you near 4mo, I think you'd want to be aiming for only three naps.
