When did your toddler stop napping?

Grace

My two year old (just turned two) has a very hard time falling asleep at time. It takes him an hour, sometimes longer than that, to fall asleep. I was putting him down at 7, then pushed it back to 8, and he still struggles. Is this a sign he may be done with a nap during the day? How old was your toddler when they dropped the nap?
