I think you need to cut the morning nap to about 45mins so that the afternoon nap is sooner. When you said you tried to cut her nap before, how long did you try that for? She might not have been ready when she was younger. She is certainly heading towards the 1 nap transition (around 12months is the av, but most have to start cutting the morning nap at this age). Do you wait to see her tired cues or do you put her down at about the same time in the morning? Maybe try something like this:
6am - wakes
9:30 - morning nap (put her down 10-15mins earlier so she can play around & fall asleep by 9:30)
10:15 - wake her from nap
1:30/1:45 - afternoon nap
3ish pm - afternoon nap ends
7pm - bedtime
How are you supposed to let them have 2 naps when their A time increases?
This is why alot are cutting morning naps so that the afternoon nap can still be taken. She is probably a little young & might not be ready for 1 nap yet so I would try to work with A times to try & fit 2 in.
She sounds overtired to me, if she's waking up earlier for the day & if she's getting ratty through her bedtime routine.
