What are your sleep times like for 10 month old babies??

DD is staying up longer and longer between naps. Usually 3-3.5hrs now. She wakes up at around 7 then has a nap around 10.30 til 12pm. So her next nap can be as late as 3.30 meaning she's waking up at around 5 which is too late because she won't be in bed until 9!!

Today I tried to get her to nap earlier but no luck!! So, what can I do?? Wake her up earlier so she goes to bed earlier??

Is she transitioning to 1 nap? Nooooooooo..........
