N.D.
Immediate nap after Mothers day out and same time give or take everyday. If he falls asleep fine, if he doesnt thats ok too. Its just for rest you dont have to sleep to rest! I let my kids even play for 2 hours in their room alone, its still rejuventaes them for the day. If he is sleeping cut it back from 3 hours to 1.5 to 2. If he doesnt nap that day put him to bed 1 hour ealier. Its a jugglin act but my kids dont nap i put them to bed at 6 or 7, if they do they get to stay up till 9 but nap is only 2 hours at most
