For kids that young I would ONLY go Disney Cruise. Carnival does cater to kids but I don't think they have programs for that young. Disney does (2 years ago). My sister took their baby. They had day and evening sitting available and all had a great time. I do echo the others above thought that say for cruising... wait till their older. You might look into something like ClubMed. Many of their villiges have accomidations for babies as well. Our family of 18 (parents, children and grandchildren) went to Xtapa in Mexico. SUPER time and I think it would be more relaxing than a cruise since you don't have to go through the hassle of getting on and off a ship with a child.
