Taking a baby on a cruise in 2026 is generally a very good idea, provided you choose the right cruise line and the baby is at least 6 months old (the standard minimum age for most sailings, or 12 months for transoceanic routes). Lines like Disney Cruise Line, Royal Caribbean, and MSC are incredibly well-equipped for infants, offering "baby splash zones," specialized nurseries with certified caregivers, and even in-cabin baby-sitting services. For parents, a cruise is one of the easiest ways to travel with a baby because your "home base" (the cabin) is always just a few minutes away if you need a nap or a diaper change, and you don't have to worry about packing and unpacking at multiple locations. Most ships also provide cribs and high chairs, and the buffet always has soft foods like mashed potatoes or bananas. The biggest challenge is that most cruise lines do not allow babies in the main swimming pools unless they are fully potty-trained (due to health regulations), so look for ships with dedicated "diaper-friendly" splash pads if your baby loves the water.
