I voted yes, but DS is too young!! I will enforce it when he is older. I do gently remind DH as well. Others have said that they rather have their napkin in hand where it is useful. Aren't you supposed to have one hand in your lap when you are eating? Drives me NUTS when DH has his other hand up around the top of his plate!!! I realize it's a bit impractical if you weren't taught that way from day one, but I cut with the knife in my right hand, fork in the left, put the knife down on the top edge of the plate, switch the fork to my right hand and put my left hand in my lap. When you think about it, that's a long ritual for taking a bite but it's second nature. I don't think I could do it any different now ...
