12mo transitioning to one nap??

[MyBreadIsEggy]

My DD had her first birthday in April. She's been a decent napper and has slept through the night since around 8mo.
She usually goes down for a nap at 9:30am until 10:30/11am and then goes down again 2:30pm until 3:30pm. She then goes to bed at 7pm and usually doesn't stir until 6:30am.
The last few days she's been really difficult to get down for her afternoon nap. Wriggling around, climbing in her cot, chattering away to herself, squealing, throwing her dummy etc. She normally fusses for a few minutes, but then just lays down and sleeps, but the last few days she's been fussing for at least half an hour before falling asleep, or not falling asleep at all.
She's also been waking multiple times in the night which hasn't happened for ages! (She's not teething at the moment or anything either).
Does it sound like she's ready to just have one nap during the day?
I don't want to drop a nap too soon!

Sounds like this
Maybe read more about it with a Google search ?
