“What exactly is wrong with spending time with your kids shbbs afternoon, after you learned with them? You can’t pressure kids with learning ALL DAY. “
Iagree that they cant learn all the time. But there are so many other things to do. Read them stories of the gedolim then. Play a torahdik game (not the ones he mentioned). Sing zemirois with them. There are lots of other good things to do rather than waste time playing games on shabbas.
