FMW.....my boys were 5 and 3 when we stopped going to the Hall. My eldest son would ask to go to the hall, only because his older cousin would ask him to go with them. I talked to my son about going, if he liked it and all, he said "yes", but he liked the candy after each meeting. I felt guilty too, because I didn't want to stifle his love for God, if it truly was there. ( He was 5) I was not interested in attending other churches so I really felt guilty, for some time. Eventually, as he became more busy with his friends at school, and parties, he never asked to go to the meetings any more. Keep your child busy with fun things....and tell him that he can make his own decisions as far as going to the hall with his grandparents. Unfortunately, grandparents have a way of making our kids, and us , feel intimidated, when it comes to meeting attendance, so we have to stand our ground.
Best wishes.......
