Yes, 11 hours sleep at night is normal for an under 18 month old. And 2-4h of daytime sleep is also normal for the age.
A 6.30pm bedtime will give you early morning. It's unusual to have it both ways - all of your evening child free plus reasonable morning wake. Given that 11h overnight is normal, it may be in the range of 10-12h, so a 5am wake up is not unreasonably early, given a 6.30pm bedtime.
The bedtime is your problem. And the read on you struggle to make bedtime later is the lack of afternoon sleep, resulting in her being exhausted by 6.30pm.
So u think dont drop naps 2 is fine just make longest one in pm?
I think she is getting ready for dropping a nap. My point is that it is the morning nap that want a dropping, not the afternoon nap.
Given she currently has a long morning nap, the transition to dropping that nap will be first of all limiting it's length. Then slowly moving the morning nap later, pushing it after lunch.
For example
9am-11am plus afternoon nap
9.30- wake up at 10.30am plus afternoon nap
10- wake up at 10.30am plus afternoon nap
10.30-11 plus afternoon nap
Then...
Early lunch then 11am single nap for as long as possible
Then...
11.30-2/3 nap
12.00-2/3 nap
