Cruising with a Baby — Age Rules and What to Expect

Most of what is written about cruising with small children is about toddlers. Under twos are a different proposition, and the difference starts before you book.

⚠️ The Age Rules That Actually Matter

This is the part to get right, because the consequence is severe. Cruise lines set a hard minimum age based on your baby’s age on the first day of the sailing, not the day you book, and a baby who does not meet it is refused boarding with no refund and no compensation.

• Six months is the usual floor. Both Royal Caribbean and Carnival require infants to be at least six months old on embarkation day for standard domestic sailings.
• Twelve months for longer crossings. Transatlantic and transpacific sailings, and itineraries with several consecutive sea days, typically require twelve months instead of six.
• Watch the sea-day count. Royal Caribbean applies the twelve-month rule to any cruise with three or more consecutive days at sea. Carnival applies it where there are more than two.
• Carnival adds an international rule. Carnival requires twelve months on any sailing that includes at least one international port, regardless of length.

🛏️ The Cabin

Ask for a cot or pack-and-play when you book rather than when you board. Most lines provide them free but stock is limited on a full sailing. A balcony is genuinely useful with a baby — it gives you somewhere to be during nap time that is not a dark room you are trapped in.

Cabins are small. A travel cot takes real floor space, and on a standard inside cabin you will be stepping around it. It is worth looking at the deck plan rather than assuming.

🍼 Feeding and Supplies

• Bring what you rely on. Formula, bottles, specific foods and your preferred nappies should come with you. Ship shops carry very little and port shops are a lottery.
• Fridges are not always cold. Many cabin fridges are coolers rather than true refrigerators. If you need to keep milk properly cold, ask guest services on day one.
• The buffet is your friend. Plain rice, pasta, fruit and vegetables are available all day, and most galleys will blend or mash on request.
• Bottled water is easier. Ask about a water package if you are making up formula.

🧸 Childcare: What Actually Exists

This is where expectations need managing. The kids’ clubs you see advertised almost always start at three and require potty training. For under twos, what is available varies enormously by line and ship — some run a paid nursery for six months and up with limited hours and capacity, and some offer nothing at all.

If childcare is part of why you are booking, verify it for your exact ship and sailing before you commit, and book the nursery slots the moment booking opens. They fill fast.

⚓ Port Days with a Baby

The honest answer is that port days get simpler if you lower your ambitions. A beach with shallow calm water and shade beats an excursion. Many families with babies stay aboard on at least one port day, which is a perfectly good use of a nearly empty ship: the pools are quiet and the crew have time for you.

If you do go ashore, a carrier is better than a pushchair almost everywhere in the Caribbean. Kerbs, sand and cobbles defeat wheels.

✅ What Makes It Worth Doing

Everything is in one place. You unpack once. Your room is a short walk from the food, the pool and the shade, and if the day falls apart you are ten minutes from a cot. Compared with an airport, a hire car and a self-catering apartment, a cruise with a baby is a genuinely easy holiday — as long as you clear the age rule first.
