THE ULTIMATE

CRUISE PACKING LIST

A comprehensive guide for babies and toddlers, ages 0–5

Hi! I’m Sarah, and I am not going to tell you to pack light. I am also not going to hand you a list of 200 things and wish you luck. What I will tell you is that I have cruised with my 2 kids under 3, and I have learned exactly where the line is between prepared and overwhelmed.

This list reflects that line. Everything on it earned its spot through real sailings, something that made a hard moment easier, a sea day more manageable, or a bedtime routine feel a little more like home. Some of it is practical to the point of boring. Some of it is a splurge that I genuinely think is worth it. I will always tell you which is which.

Pack what works for your family. Skip what doesn't. But read the notes, because sometimes the thing that looks optional is the thing you'll wish you had at 11 pm in the middle of the ocean.

Before You Pack

The Packing Math

Outfits

Days sailing + 1 extra per 3 days  — halve it if you bring a wash bag

3 nights = 4  |  5 nights = 7  |  7 nights = 9

Swimwear

Always 2  — rashguard counts, swim dries fast

Pajamas

1 pair per 2 nights, minimum 2  — 3 nights = 2, 5 nights = 3, 7 nights = 4

Diapers

(Sailing nights + travel days) x 7 + 10–20% buffer  — 7 nights + 2 travel days = 63–69 diapers

Pull-Ups

(Sailing nights + travel days) x 5 + 10–20% buffer  — 7 nights + 2 travel days = 44–48 pull-ups

Pro tip

Split diapers across your diaper bag, carry-on, and checked bag. Ships sell diapers onboard but at a significant markup.

Sleep

The make-or-break category. Get this right and the whole trip shifts.

White Noise Machine All ages Must-Have

Ship hallways are louder than you expect. Non-negotiable at any trip length.

Magnetic Cruise Approved Fan All ages Splurge

Cruise cabin airflow is not great. A small magnetic fan clips right to the metal walls and makes a real difference for naps and bedtime.

Sleep Sack Babies + Toddlers 0–3 Must-Have

Whatever your child sleeps in at home, bring it. Keeping the sleep routine as familiar as possible makes a real difference in an unfamiliar cabin.

Baby Sleep Sack — babies
Toddler Sleep Sack — toddlers
Security or Comfort Item All ages Must-Have

Whether it's a lovey, a light blanket, or a stuffed animal -- bring whatever your child already sleeps with at home. Don't buy anything new for this one. The familiar scent and feel does serious work in an unfamiliar cabin. This is the item most parents forget and most regret leaving behind.

Pack N Play Sheets Babies 0–12mo Splurge

Every cruise line provides a different sleep space. Most (Royal Caribbean, Carnival, Norwegian, Princess) use a roughly 39" x 28" play yard with a thin firm pad. Disney sometimes provides a full-size crib depending on the ship. MSC varies by ship class. When in doubt, bring both sizes.

Mini Crib Sheet — fits most cruise line play yards (~39" x 28")
Standard Pack N Play Sheet — fits Disney full-size cribs and larger play yards
Inflatable Toddler Bed Toddlers 12mo+ Splurge

Cabin dependent -- you will need enough floor space to make this work. If your cabin is on the smaller side, check my Instagram for a hack using the cabin couch that works just as well.

Sun + Swim

You will spend a lot of time outside. Protect the small humans.

Mineral Sunscreen All ages Must-Have

Many Caribbean and Mexican ports require reef-safe sunscreen to enter the water. Mineral formulas cover you everywhere. Blue Lizard is what I use on my own kids.

Blue Lizard Kids Sunstick — great for faces
Blue Lizard Lotion — for babies and sensitive skin
UPF 50 Swimwear All ages Must-Have

Reapplying sunscreen on a wet, squirming toddler every 80 minutes is a special kind of impossible. UPF 50 swimwear cuts that frequency dramatically. Rashguards and full-coverage suits count -- if the skin is covered, it's protected.

Baby Girl

Baby Boy

Kids

Wide-Brim Sun Hat All ages Must-Have

A hat without a chin strap is just a hat your child throws into the ocean. Make sure yours has one.

Swim Diaper (reusable) 0–2yr Must-Have

Required if your child is not fully potty trained -- most cruise ship pools and splash pads will turn you away without one. Bring reusable. Rinse and reuse. 2 is enough for any trip length.

Water Shoes 12mo+ Must-Have

Hot pool decks, rocky beaches, and mystery textures in port. Water shoes handle all of it.

After Sun Lotion All ages Must-Have

Even with great sunscreen and UPF swimwear, prolonged sun exposure shows up. Have this ready before you need it.

Feeding

The dining room is great, but not at every meal. Come prepared.

Snack Holders 9mo+ Must-Have

One of the most practical things you can bring. Head to the buffet in the morning, grab cereal, fruit, or snacks, and you have food for the whole day without carrying a bag of groceries.

Toddler Restaurant Essentials Kit 12mo+ Splurge

This kit is a game changer. It comes with food scissors, which you absolutely need on a cruise for cutting up food quickly at the table. Important: if you are flying to your cruise, the scissors must go in a checked bag -- they will not make it through TSA in a carry-on.

Reusable Snack Bags All ages Must-Have

A more sustainable alternative to Ziploc bags. Great for grabbing extra snacks from the buffet, storing half-eaten items, or keeping port-day snacks organized.

Reusable Pouch Toppers 4mo+ Splurge

Grab any snack pouches you already have and attach these to the top -- they make them resealable and kid-drinkable. If flying through TSA and bringing pouches in your carry-on, make sure they are 3.5 oz or less.

Travel Utensils 12mo+ Must-Have

The ship has utensils but having a set sized for small hands makes mealtimes easier, especially at the pool or on excursions. Whatever you already have at home works fine.

Toddler Cup 12mo+ Must-Have

Whatever toddler cup you already use at home is fine -- just make sure it's insulated since ship ice melts fast in the heat. Honest disclaimer on this one: it's not fully spill-proof, but it's the best I've used. Don't let it get dropped.

Formula Dispenser Babies 0–12mo Must-Have

Pre-measure formula into individual servings before you leave. The fewer steps you have at 3am the better.

Portable Bottle Warmer Babies 0–12mo Must-Have

The ship's hot water in the cabin can work in a pinch, but having a portable warmer means you are never hunting for a solution at 2am.

UV Water Purifier Bottle Babies 0–12mo Splurge

Not 100% necessary, but a genuine upgrade -- especially for formula. Ship water is generally safe, but this uses UV light to purify the water giving you extra peace of mind.

Portable High Chair 6mo–2yr

In my experience cruise ships always have high chairs available -- I have never had trouble getting one. That said, if you prefer your own or want the flexibility, here is a solid option.

Laundry & Cleanliness

One blowout. One sunscreen explosion. One dropped ice cream. You need a plan.

Wet Bags All trips Must-Have

One for dirty swimsuits. One for wet clothes. One for the truly catastrophic scenarios. You will use all of them on every sailing regardless of trip length.

Portable Stain Remover Pen All trips Must-Have

Buffet mornings. Need I say more.

Scrubba Wash Bag 4+ nights Must-Have

This is the single item that changes your entire packing math. Instead of packing an outfit for every single day, you pack half as many and wash every 3 nights. It takes about 3 minutes, uses barely any water, and means you are not checking a giant suitcase or overpaying for the ship's laundry service. I bring it on every sailing of 4 nights or more and it has never let me down.

Kids Laundry Detergent Sheets 4+ nights Must-Have

The Scrubba needs something to work with. Detergent sheets are the only travel laundry format that makes sense -- no liquid to leak, no TSA issues, gentle enough for kids' clothes and sensitive skin.

Clothes Clips Balcony cabins Splurge

If you have a balcony, this is a must. Hang washed items overnight and they are dry by morning. The ocean air does the work for you -- no dryer needed.

On-the-Go

Excursions, embarkation days, port days. You are moving. A lot.

Travel Stroller Walking age and under Must-Have

Your everyday stroller is probably too big for ship elevators, cobblestone ports, and gangways. A compact travel stroller is the right tool. If you are traveling with two kids, the double option is a game changer for long port days.

Travel Stroller (double) — if traveling with two kids
Baby Carrier 0–3yr Must-Have

Tender ports, stroller-unfriendly beaches, and busy embarkation days all demand this. There will be a moment on every cruise where you need your hands free and the stroller is not an option.

Day Bag / Backpack All ages Must-Have

Your diaper bag works perfectly fine for this. If you are looking for an upgrade, I am obsessed with the Ink and Barrel -- it is the bag I use for every trip and it fits everything without feeling like you are carrying a hiking pack.

Ink and Barrel 22L Backpack — my personal pick
Family Passport Holder All ages Must-Have

Keeping track of passports, boarding passes, and sea pass cards for a whole family at embarkation is stressful. Having everything in one place makes the whole process significantly smoother.

Magnetic Door Organizer Smaller cabins · 4+ nights Must-Have

Cruise cabin doors are magnetic and storage space is limited -- especially in inside and oceanview cabins. This organizer sticks right to the door and gives you a place for sunscreen, wipes, snacks, diapers, and all the small things that would otherwise take over every flat surface.

Toddler Harness Backpack 18mo–3yr Splurge

I have not personally used one but I can absolutely see how these would be incredible for cruising and excursions. Gangways, tender docks, and crowded port streets are exactly what these were designed for. No judgment on how we keep our kiddos safe.

Health + Wellness

Ships have medical centers. They charge cruise prices. Come stocked.

Children's Pain Reliever + Fever Reducer All ages Must-Have

Bring more than you think you need. The ship pharmacy will have it but at a significant markup -- and it may not be the formulation your child is used to.

Pedialyte Packets 6mo+ Must-Have

Toddler + heat + not drinking enough water is a situation that happens faster than you expect on a cruise. Powder packets dissolve in any water bottle and do not require refrigeration. Toss a few in your day bag every port day.

Mini First Aid Kit All ages Must-Have

Pool decks are slippery. Port cobblestones are unforgiving. A compact kit handles the scrapes, cuts, and minor situations that happen on every family vacation without a trip to the medical center.

Mosquito Repellent Stickers Caribbean + Tropical Must-Have

Far easier than trying to spray repellent on a squirming toddler in a port. Stick them on clothing and you are covered. Essential for Caribbean and tropical itineraries.

Hand Sanitizer Spray All ages Must-Have

Ships are clean but they are also shared spaces. Spray is easier than gel for small hands and fits in any day bag pocket.

Wearable Digital Thermometer All ages Must-Have

Fast, accurate, and wearable -- so you can monitor a fever on a sleeping child in a dark cabin without waking them up. Worth every ounce of luggage space.

Shampoo + Body Wash All ages Must-Have

Ship-provided toiletries are not formulated for baby skin. Bring your own. This Honest bundle covers shampoo, body wash, and lotion in one.

SPF Lip Balm 12mo+ Must-Have

Wind, sun, and salt air wrecks little lips fast. Apply before every pool session and every excursion. Easy to forget, impossible to ignore once they need it.

Entertainment & Play

The ship is the entertainment. This list is intentionally short.

Magnetic Blocks 18mo+ Must-Have

No loose pieces. No pieces rolling under the cabin door. Magnetic toys are the only travel toy logic that holds up at sea. Works on the cabin floor, the dining table, the pool deck -- anywhere.

Pop The Target Toy 2yr+ Must-Have

A compact, endlessly replayable toy that works in the cabin, at the dining table, or on a sea day. Small enough to toss in your day bag.

No Mess Water Books 18mo+ Must-Have

Water-activated coloring. No mess, no markers left uncapped, no ink on the white ship linens. A travel miracle. Works at the pool too -- just dip and paint.

Inflatable Pool + Water Blasters Balcony cabins · 0–3yr Must-Have

Balcony cabins only -- and one of the best kept secrets for cruising with babies and toddlers. A contained private splash space with an ocean view. Add the water blasters and you have an activity that will keep small kids happy for an entire sea day.

Water Blasters — pairs perfectly with the pool
