Do you notice any difference on days when her naps are different? The reason I ask is that by 9/10 months a lot of los are starting to work on the 2-1 transition (not that it happens at this point, just that the groundwork starts) and sometimes a short/long nap combo works better than 2 naps the same length. For various reasons, my children have always had a short am/long pm combination, but some find that it works better the other way around. If that was something you wanted to try, the long nap would be 2h, or maybe a bit more, and the short nap would be up to an hour (ds is on 30 minutes and has been since about 8 months, but I'm not sure he's the best model as his sleep is lousy!
).
Other than that, in my experience there are 3 main reasons for ew: teeth, ot and first a time being too short. In the first day you posted, it looks like her first a time was only 2h45 - is that typical? I think that by 9 months most are up to about 3h a time, if not a bit more.
Ot - do you know whether she is low sleep needs or high sleep needs? My dd1 would probably have been ot on the amount of sleep your dd is getting, but she is ridiculously high sleep needs! Dd2 would likely have ended up ot from the length of a to bed time - she is touchy, and therefore we had a lot of issues when her afternoon was too long.
Finally, teeth - this was a big culprit for dd2, and I think is one of the big problems with ds at the moment. Is your dd teething?
As for waking from naps, I always did/do (when I have the option!) as I find the day works so much better if I do. I have found that waking them gets the day into a predictable pattern and it sets their body clocks which makes life easier - it might help you when you get back to work if her body clock is set.
Hope some of this helps - I have just realised that I have rambled on with loads of possibilities!
