When to cut naps

Will be 1 year in 2 weeks. Takes 2 naps still (is very tired for both, miser ale if he takes one nap mid day) so I know he isn't ready yet. I've read online 15 months is normal for transition to 1 nap but most of my friends babies are at 1 nap at a year and are pressuring me but I know for a fact he's tired for both naps and sleep well for both and at night. He's up at 6 am so he's tired by 10 or 11. Then again at 3pm takes an hour nap each time. In bed by 8pm

When did you transition? I'm trying to follow his lead and not rush it . What method did u use?
