My son still naps 3 hrs. From 1 to 4. He wakes up at 7:45 to 8. Naps at 1. Wakes up at 4 and goes go bed around 8:30.
It’s rare for my son too as well. But I definitely won’t let it go past 1.5hrs or 5pm. Otherwise bedtime is a mess. Lol
Instead of naps we do quiet time or down time. He goes in his room for about an hour and a half, he can play all he wants but he has to stay in his room unless it’s an emergency
My son is exactly the same. I dropped his nap before his 3rd birthday.
