I think some of her awake times are too long for 7 months and could be causing overtiredness, which causes short naps, resulting in early wakings.
Looks like the first A time is about 2-2.5h which probably isn't bad.
But then you have a 3.25h awake time, after only a 45 minute nap. I would think that would be way too long. I am having trouble figuring out my DS's awake times, but I would think after a short nap you would probably only have about 2-2.5h again.
Then, you have 3.5h before the third nap which again, I would say is too long after a 30 minute nap.
I am definitely not a nap expert (we're having problems of our own
) but I would think that too long A times, and overtiredness are causing your problems.
