My dck all love rice and I serve it several times a week ... Today in fact ... For the babies I use the milder bibs with the scoop on the bottom and there is very little mess the older one are told to eat over their plates and I vacuum at the end of the day ..... However Spitting would not be tolerated and the child would be removed from the table and made to wait till every one else is finished to have their lunch ... Same would go for any one else that thought this might be a fun thing to do. Generally all I hav to do to get my dcks to stop something is to give them the "look" .
