8 hours of sleep is pretty good!

Mr W rarely napped at that age, went to bed at 9 pm, woke up at midnight and 3 am and was wide awake by 6am. It was a battle until he turned 3.5 years when he would go to sleep at 9pm and sleep all night to 6am. Some days he sleeps in to 8am. There are still nights when he comes in around 3am to wake us.
