Melina, i hate to say this but your travel agent should know that swim diapers are not allowed in the pools, it is common knowledge, its for health reasons. quite a few families will bring their own little blow-up pools for the little ones to splash around in. She can sit on your lap and you can stick her feet in the water. Your travel agent should make all the necessary arrangements for a porta-crib in your cabin. Public ladies rooms have baby changing stations. As for packing suggestions, bring enough diapers to last the duration of the cruise, pack lightweight clothing, little sundressess are ideal, shorts, hats, sunscreen. As for her food, again take that up with your travel agent, and just to be sure, once you get onboard go to see the Maitre D directly and tell him your needs. I would also suggest you ask this question over on our family cruising board.
