Hi there:) Your routine really looks good to me. In fact, we were doing something similar at 8 months. Developmental milestones can affect sleep a lot, especially when they have just picked up a new skill and want to practice, practice, practice. We had the same experience when DD learnt to sit, crawl and now stand. If she is even a wee bit UT, she will keep standing over and over and we have to just keep laying her down.
When she wakes at 1am, how do you settle her? Does she have any night feeds? Even if she was horribly OT, hun, I doubt that she would be waking up hourly. That sounds more like discomfort actually. Sure no more teeth on their way?
