A bit of both. With kinder days we have to keep her awake sometimes when she really would like to have a nap but generally she goes down sometime between 12-1. The other morning she woke up at 5 am and was absolutely shattered by 10.30 so I asked her if she wanted a sleep and she said yes, so I put her to be at 10.45. She slept for 3 hours and was fine for the rest of the day. So if I can leave it up to her then I will otherwise she goes down when it's time.
