When did your toddler drop their nap?

My 2yo (24months) is resisting naps but does fall asleep after about 15/20mins of he laying down. And he generally sleeps for more or less an hour. But then at bedtime lays awake for over an hour before he finally drifts off, just singing/chatting to himself. He’s quite happy and content, it just takes forever for him to fall asleep 😴 So now I’m wondering if we should see how he does without a nap and consider dropping it completely 🤷🏼‍♀️
