A note before we start: we haven’t taken Nayeli on a cruise yet, so this guide is built entirely from cruise lines’ official policies, cross-checked directly against their FAQ pages rather than secondhand summaries, since several blogs online have this wrong or out of date.

Ask five different cruise lines “can you take a baby on a cruise” and you’ll get five different answers, and a fair amount of contradictory information circulating online, especially around MSC. Here’s what’s actually true, company by company, verified straight from each line’s own policy pages.
Minimum age to take a baby on a cruise
The near-universal rule across the cruise industry is 6 months old on embarkation day, with one major exception we’ll get to. This isn’t a soft guideline, it’s checked at the pier with ID, and cruise lines do turn families away if a baby doesn’t meet it, even on last-minute bookings made in good faith.
- Standard itineraries: 6 months old minimum on the first day of the cruise
- Transatlantic, transpacific, or itineraries with 3+ consecutive sea days: 12 months old minimum
- Age is calculated by the exact embarkation date, not the booking date, a baby who turns 6 months two days after sailing does not qualify
- The rule exists regardless of how healthy or advanced your baby is for their age, it isn’t assessed case by case
Cruise lines compared by minimum age
| Cruise line | Standard sailings | Long / transoceanic sailings |
|---|---|---|
| MSC Cruises | No minimum age | 2 years old (11+ nights only) |
| Royal Caribbean | 6 months | 12 months |
| Carnival | 6 months | 12 months |
| Disney Cruise Line | 6 months | 12 months |
| Celebrity Cruises | 6 months | 12 months |
| Princess Cruises | 6 months | 12 months |
Policies are updated periodically by each line, always confirm directly on the cruise line’s own site before booking if your baby’s age is close to a threshold.
MSC: the one line with no age minimum
This is the detail most worth getting right, because a lot of what’s published online about MSC is outdated or simply wrong. MSC updated its Minors Policy on 15 May 2025, and the current, official rule is straightforward: infants under 2 years old are admitted on board with no minimum age at all, on any sailing shorter than 11 nights. The only age restriction that exists is for longer voyages.
- Sailings under 11 nights: no minimum age, a newborn can technically sail
- Sailings of 11 nights or more: the minor must be at least 2 years old (24 months) on embarkation day, infants under 2 are not permitted at all on these itineraries
- Babies and infants aged 2 and under cruise free of charge on MSC
- Ages are verified at embarkation using ID or a birth certificate, same as every other line
Why the age minimum exists
It isn’t arbitrary. Cruise ships carry only limited medical facilities, generally equipped for adult and older-child emergencies rather than specialized infant or neonatal care. The reasoning behind the 6 and 12 month thresholds comes down to one thing: distance from a proper hospital.
- A very young infant with a sudden high fever, days from the nearest port, is the exact scenario these rules are built to avoid
- Longer itineraries with 3 or more consecutive sea days mean longer stretches without access to land-based emergency care
- The rule is enforced strictly and uniformly, not assessed on a baby’s individual health or a parent’s confidence
Taking a baby on a cruise under 6 months
If your baby is younger than 6 months, the honest answer is simple: MSC is currently your only mainstream option. Every other major line, Royal Caribbean, Carnival, Disney, Celebrity, Princess, enforces the 6-month rule without exceptions, regardless of circumstances or how the booking came about.
- Choose a shorter itinerary, ideally under a week, with frequent port days rather than long stretches at sea. More ports means more access to land-based care if you ever needed it, and shorter days at sea generally suit a young baby’s routine better anyway.
- Ask about a doctor’s note in advance. Some bookings for infants under 6 months may require a fit-to-travel letter from your pediatrician, confirm this with MSC directly rather than assuming, policies can vary by region and itinerary.
- Check what’s actually available onboard for a very young baby. Formula, sterilizing equipment, and a crib are usually available on request, but confirm before sailing rather than after, availability can be limited on smaller or older ships.
- Consider your own recovery timeline too, if you’re postpartum, the physical demands of a cruise, embarkation queues, stairs, uneven gangways, are worth weighing honestly against how you’re feeling at the time of travel.
Best cruise lines for a baby
Age minimum aside, some lines are genuinely better equipped for babies than others, in terms of nursery facilities, cabin options, and onboard flexibility.
The “It’s a Small World” nursery accepts babies from 6 months, staffed and bookable by the hour. Strongest infant-specific childcare infrastructure of any line, though it comes at a premium price point.
The only realistic choice under 6 months, and often runs kids-sail-free promotions that extend to infants and toddlers, worth checking before booking elsewhere.
Royal Babies & Tots Nursery for younger children, plus frequent “kids sail free” promotions and private island stops designed with families in mind.
Strong value at the entry-level price point, family-oriented culture, and staff generally well accustomed to young children, though nursery-style infant care is more limited than Disney or Royal Caribbean.
Practical essentials once you’re booked
Age rules aside, a few practical details make the difference between a smooth cruise with a baby and a stressful one.
- Request a crib or pack-and-play when booking, not on arrival, availability is limited and first-come, first-served on most ships
- Ask about connecting or family cabins if you’d rather not share a standard-size room with a crib squeezed in
- Bring your own baby food and formula as backup, most lines stock basics but variety and specific brands can be limited, especially mid-cruise
- A lightweight, foldable stroller works far better onboard than a bulky travel system, cabin corridors and elevators are narrow, and storage space in a standard cabin is limited
- Balcony cabins need extra vigilance, most lines fit high railings and child locks, but check this specifically when booking if you have a baby who’s mobile or soon will be
FAQ
Can you take a baby on a cruise?
Yes, but the minimum age depends on the cruise line. Most major lines require 6 months minimum, 12 months for transatlantic or long sea-day itineraries. MSC has no minimum age at all on sailings under 11 nights.
What age can a baby go on a cruise?
Generally 6 months old for standard itineraries on most lines, 12 months for transatlantic, transpacific, or itineraries with multiple consecutive sea days. MSC is the exception, with no minimum age on sailings under 11 nights.
What is MSC’s baby age policy?
MSC has no minimum age for infants on sailings under 11 nights. For sailings of 11 nights or more, the child must be at least 2 years old on embarkation day, infants under 2 aren’t permitted on these longer itineraries at all.
Can I take a baby under 6 months on a cruise?
Only on MSC among the major lines. Every other line, Royal Caribbean, Carnival, Disney, Celebrity, Princess, enforces a strict 6-month minimum with no exceptions, checked at embarkation.
Which is the best cruise line for a baby?
Disney has the strongest dedicated infant nursery facilities from 6 months. MSC is the best fit if your baby is under 6 months, since it has no age minimum on shorter sailings. Royal Caribbean and Carnival both offer solid family value with kids-sail-free promotions.
Does a baby cruise for free?
It depends on the line. MSC carries babies and infants aged 2 and under free of charge. Other lines generally charge the full cruise fare for infants, though promotional “kids sail free” offers sometimes extend to babies too, worth checking at booking.
“The cruise line you pick matters more than almost anything else when your baby is very young, it decides whether you can even board.”
If your baby is 6 months or older, you have the whole industry to choose from, and it’s worth comparing nursery facilities and family perks rather than just price. If your baby is younger than 6 months, MSC is currently the one door that’s open, though the flexibility is worth weighing carefully rather than treated as a simple green light. Either way, book the crib, pack backup formula, and keep the itinerary short and port-heavy for a first cruise with a baby.
