Travelling to Bali with a newborn takes more preparation than a trip with an older child. Babies under 6 months have developing immune systems, limited vaccination coverage, and specific needs around feeding, sun exposure, and sleep. Here's a practical checklist based on paediatric travel guidance and real parent experience.

Before you go: vaccinations and travel clinic

Visit a travel clinic or your GP at least 6–8 weeks before departure. Newborns may not be eligible for all travel vaccinations yet:

Routine vaccines: Ensure your baby's scheduled vaccinations (DTaP, Polio, Hib, PCV, Rotavirus) are up to date for their age. Some can be given early if travel is imminent — ask your doctor.

Hepatitis A: Not recommended before 12 months. Protect your baby through hygiene and safe food/water practices.

Japanese Encephalitis: Not licensed for babies under 2 months (some brands under 12 months). Mosquito protection is your primary defence.

Typhoid: Not recommended before 2 years. Again, food and water hygiene is the main protection.

Malaria: Bali is classified as very low risk for malaria. Prophylaxis is not typically recommended, but confirm with your travel doctor based on your specific itinerary.

Mosquito protection for newborns

Dengue fever is the main mosquito-borne risk in Bali. There is no vaccine available for infants, so prevention is everything:

For babies under 2 months, do not use chemical repellents. Use physical barriers: mosquito nets over the cot, long sleeves and trousers in light fabric, and air-conditioned rooms with closed windows at dawn and dusk.

For babies over 2 months, baby-safe repellents with up to 30% DEET can be used on exposed skin (not hands, face, or under clothing). Reapply after swimming or sweating.

Water, formula, and feeding

Never use tap water in Bali for anything that goes in your baby's mouth — formula, drinking, sterilising, or rinsing bottles. Use sealed bottled water (check the seal is intact) or boiled water that has cooled.

If you're formula-feeding, bring enough from home for the full trip. Familiar brands may not be available in Bali, and switching formula mid-trip can cause digestive issues. If you're breastfeeding, stay hydrated — the heat and humidity increase your fluid needs significantly.

Pack a portable bottle steriliser or sterilising tablets. Most villas have kettles; higher-end hotels can provide sterilising equipment on request.

Sun protection

Babies under 6 months should be kept out of direct sunlight entirely. Bali's UV index regularly exceeds 11 (extreme). Use shade, UPF-rated clothing, and a wide-brimmed hat. For babies over 6 months, apply broad-spectrum SPF 50+ sunscreen to exposed areas, reapplying every 2 hours.

Schedule outdoor activities before 10 AM or after 3 PM when UV is lower. Midday is for indoor time, naps, or shaded poolside rest.

Medical facilities and pharmacy essentials

BIMC Hospital (Kuta) and Siloam Hospital (Denpasar) have English-speaking paediatricians and international-standard emergency departments. Save their phone numbers in your phone before you arrive. Both accept international insurance and can handle most paediatric emergencies.

Bring a baby-specific travel medical kit: infant paracetamol (Calpol/Tylenol), oral rehydration sachets, saline nasal drops, nappy rash cream, digital thermometer, antiseptic wipes, and any prescription medications with a doctor's letter. Bali pharmacies stock some basics, but availability of specific infant formulations is unreliable.

Transport safety

This is the area most parents underestimate. Bali taxis, Grab, and Gojek do not provide child car seats. Holding a newborn on your lap in a vehicle is not safe — full stop. Pre-book every car journey with a fitted rear-facing infant capsule. From airport pickup to day trips, every ride with your newborn needs a proper restraint.

Sleep and accommodation

Request a cot when booking accommodation and confirm the type (wooden hotel cot vs. foldable travel cot). Bring your own fitted cot sheets — sizes vary. A portable white noise machine or app can help mask unfamiliar sounds. Keep the room cool (around 20–22°C) with air conditioning, and use a sleeping bag instead of loose blankets.

Packing checklist for Bali with a newborn

Nappies (bring enough for the first few days — Bali stocks Pampers and MamyPoko), wipes, nappy bags, portable changing mat, formula and sterilising supplies, infant medication kit, mosquito net, baby-safe repellent, sunscreen (6 months+), UPF clothing and hat, baby carrier or sling, lightweight muslin wraps, passport and insurance documents, and a copy of your baby's vaccination record.
