Seems like we are doing a pretty good job at indoctrinating the kids. While at my parents, DD was watching a cartoon (I remember watching that cartoon when DD's age, LOL) where all the animals brought Rabbit all different kinds of delicious food: nuts, fruits, cakes and pies. DD looked at it and told Mom, "Grandma, this is a beautiful shabbos party."
On another occasion, I was reading the kids the book about Kipper and his flashlight. Both kids looked at the flashlight and asked me, "Is Kipper looking for chametz?"
