No naps

My boy hasn’t had a daytime nap for nearly 2 months. Is anyone else on no naps? He would wake up around 7/7.30, have a nap after lunch so 12.30-2pm and he would be a nightmare to get to sleep, sometimes finally falling asleep at 10/10.30pm! Since he’s not had a nap he sleeps at least 12 hours mostly 13 hours. I feel like him stopping naps around 18 months is way to early. Can anyone else relate??
