My son is 2y8m now, he has nap about 1.5h in nursery during weekdays, no nap on weekend, unless we take him to drive around, he only can sleep in the car. we use a childminder this week, he doesn't want to sleep at all. He become quite after dinner, falls sleep in 2 minutes around 8 pm, no struggle at all and not wake up until next morning 8 am.before we drop his nap, he can talk at least half hour on bed, sometimes run away.I think he become easier to sleep than before. but everyone is different. I think you can try it on weekend, if he is not ready, he can still have nap.
