well this age seems to be a bit tough for naps. Is she learning a new skill?
All you can try is different times, may be if she has woken at 7am then 9:30 is too early.
could you try 10am nap till11
nap 2-3:30
the NW do seem like overtired from not enough day sleep. if you absolutely can not find a time that she will sleep in the morning, then put her down no later then 12 and hope she sleeps a few hours. if not, then maybe you could sneek a catnap in before dinner, or move bedtime up very early.
