Infants must be at least 6 months of age at the time of embarkation in order to sail. Children must be at least 12 months of age at the time of embarkation to sail on trans-ocean crossings and remote itineraries, where there are more than 2 consecutive sea days. We do not carry baby food or formula on board our ships.

Getting a baby on a cruise requires careful planning regarding age, documentation, and packing. First, check the minimum age requirement; most cruise lines (like Royal Caribbean or Carnival) require infants to be at least 6 months old on the day of sailing, while transoceanic or remote itineraries often require a minimum age of 12 months. For documentation, you will need a valid passport for the baby, even for "closed-loop" cruises that start and end in the same U.S. port, as a birth certificate may not be sufficient for all foreign ports of call. When booking, you must add the baby as a passenger, even if they are sleeping in a crib; while some lines offer "infant fares," you will still pay port taxes and fees for them. You should request a "pack-and-play" or crib for your stateroom in advance. In terms of packing, you must bring everything the baby needs, including diapers, wipes, and formula, as these items are rarely sold on board or are very expensive. Many modern ships offer "baby-friendly" splash pads, but be aware that children in diapers (including swim diapers) are strictly prohibited from most main pools due to health regulations.
