I am not positive but i have heard that Carnival will take childre 2yrs. into there Camp Carnival. Never heard "HAS TO BE POTTY TRAINED"... How rude.... I again have never taken children on a cruise. But I have never had a problem with Children on any cruise I have taken either. Call Carnival and take the child and have a great vacation. I love Carnival....... Even with Children allowed. I have 5 grand children and love to see the little ones there too.
