make things very clear. first thing is a long nap in the afternoon b4 yomtov. if he doesn’t 4 any reason there is nothing to speak about. tell him you will go by – hour by hour. most young children do go to shul at 11.00 pm. tell him each hour his abba will see how he – the boy is doing. sometimes a young group of children will recite tehillim also. that’s fine. as soon as the abba notices that his son cannot sit any longer- it’s time to go home. let him know beforehand it’s not a punishment to go home early. it could be a beautiful learning experience for both father and son. also the father should be willing to go over the boy’s parsha and yomtov sheets he brings home from school. which means he might not learn with his own chavrusa. hatzlocha.
In the future, please refrain from using such shorthand. Using 4 as a replacement for the word “for” (and other such maneuvers) often leads to posts getting deleted on the spot
