Jessica,
I don't think you are misreading her at all. As long as she isn't having NWing, she's doing fine. She needs a lot of sleep, which isn't uncommon at this age. Remember, from 1-3 months LOs need about 15-18 hours of sleep. I don't necessarily know what I would count as her day time start - probably that 6:30 waking since you put her to bed at 6:30. Many LOs shortest A times are first thing in the morning. They are still catching up on their night time sleep.
Do you remember what her Temperment is?
Sounds like Leia is doing great! Enjoy it!
