Travelling to Thailand with an infant.

The flight, and when to take it

The single best decision a family with an infant makes is the flight time, and it is made months before anything else. From the western metros, Mumbai, Delhi, Ahmedabad and Bengaluru, Bangkok is roughly four and a half to five and a half hours; from Kolkata it is under three. That is short enough that a daytime flight with a baby is entirely manageable and short enough that the popular late-night departures are a trap: you arrive at one or two in the morning, clear immigration with a sleeping infant, reach the hotel at three, and lose the whole of the first day to a wrecked routine that takes three days to rebuild.

We push families with children under two onto morning or early afternoon departures wherever the schedule allows, accepting a higher fare as the cost of a functioning first day. Bassinet seats on the bulkhead should be requested at booking and reconfirmed at least twice, because they are allocated by weight limits and by luck. Fast-track immigration at Suvarnabhumi, where available, is worth its fee for exactly this passenger. And the drive from the airport into central Bangkok runs forty minutes to an hour, longer in the evening peak, which is a real consideration when a baby has already been in a seat for five hours.

What to bring, and what to buy there

Families routinely overpack for Thailand and it is worth knowing what is genuinely available. Bangkok's supermarkets and pharmacies, including the large chains in every mall and the standalone chemists on every commercial street, carry international-brand infant formula, nappies, wipes, baby toiletries, sterilising equipment and jarred or pouched baby food. Stock is good in Bangkok, good in Phuket and Chiang Mai, and thinner on the smaller islands and in resort areas away from towns, where the resort shop marks everything up considerably.

The things to carry from India are the specifics rather than the staples: the exact formula your baby is established on, because switching brands mid-trip is not worth the risk even when a comparable product is available; any prescribed medication with the prescription; a familiar teether, blanket or sleep toy; and, for Indian families in particular, the home foods a weaning baby actually eats, which are not sold in a Bangkok supermarket. Ragi, sooji, moong dal khichdi mixes and the family's own masala-free preparations travel well in sealed containers. Where the family is staying in a villa or serviced residence with a kitchen, or travelling with a cook, this stops being an issue entirely, which is one more argument for those formats with a baby in the group.

Hotel rooms, cots and the practical set-up

Thai hotels are unusually good with infants, but the good outcome depends on asking in writing and confirming rather than ticking a box. We request the cot by type, a full-size cot rather than a folding travel cot where one is available, and confirm it will be in the room at check-in rather than delivered later. We ask for a high chair for the room as well as the restaurant, a bath tub or a bath support if the room has only a shower, a bottle steriliser or a kettle that can be used for one, and a small refrigerator that actually chills rather than a minibar cooler that does not.

Room choice matters more with a baby than at any other stage. A one-bedroom suite or a connecting room lets parents have an evening once the baby is down, which is the difference between a holiday and a long stay in a dark room. Ground-floor or low-floor rooms shorten every lift journey with a pram. Rooms away from lifts, bars and function rooms protect the sleep. Blackout curtains are standard in Thailand but the quality varies, and a travel blackout blind takes no space. For longer stays, the serviced residences in the Sukhumvit corridor solve most of this at once with a kitchen, a washing machine and space for the pram.

Heat, water and skin

Thailand's heat is the main clinical risk to an infant on this trip, and it is a real one. Bangkok in April and May regularly sits above thirty-five degrees with humidity that prevents effective cooling, and a baby dehydrates faster than an adult and cannot tell you. The practical discipline is the same one we give every multi-generational group but tighter: nothing outdoors between roughly eleven and four, shade and a fan rather than direct sun at any hour, frequent feeds and fluids, light cotton clothing, and a hat. Prickly heat is extremely common in visiting infants and responds to loose clothing, cool baths and air conditioning rather than to creams.

On water: tap water in Thailand is not for drinking, and for an infant that extends to preparing formula. Use bottled water, boiled, or the hotel's filtered supply confirmed as suitable, and be careful with ice outside good hotels and restaurants. Swimming pools are generally well maintained at the properties our clients use; the sea is fine for a paddle on a calm Gulf beach and unsuitable for an infant on an Andaman beach in the monsoon. Sun protection for babies under six months is shade and clothing rather than sunscreen, and after six months a high-factor mineral sunscreen applied to small exposed areas. Mosquito protection matters in the wet season: dengue is present in Thailand, so a cot net, screened rooms and an infant-appropriate repellent used as directed are sensible rather than alarmist.

Paediatric access, which is the reassurance most parents want

The strongest argument for Thailand with a baby is medical. Bangkok's private hospitals are among the best in Asia and are set up for international patients in a way that Indian families find immediately familiar: English-speaking staff, walk-in and appointment paediatric departments, and no drama about payment by card or insurance. Samitivej Sukhumvit up Soi 49 is particularly well regarded for paediatrics, Bumrungrad International on Soi 3 is the name most Indian visitors already know, and Bangkok Hospital on New Phetchaburi Road is the other major international-facing option. In Phuket, Chiang Mai and the larger resort towns the private hospitals are good; on the smaller islands you will find clinics rather than hospitals, which is a genuine consideration when choosing a destination with an infant.

Before travel we do four things for any family with a baby. We identify the nearest suitable hospital to each place they will sleep and time the route by car at the worst hour of the day. We hold a written list of the child's medications, allergies, weight and vaccination status. We confirm the travel insurance covers infants and covers outpatient paediatric visits, not only emergencies. And we ask the family's paediatrician in India for a short travel note, which is useful both at immigration if medication is being carried and at a Thai hospital if anything needs explaining quickly.

The pre-departure list

• Passport for the infant and confirmation that the visa exemption applies to them as it does to adult Indian passport holders; verify current rules before booking.
• TDAC arrival card completed for every traveller including the baby, within seventy two hours of arrival.
• Daytime flight, bassinet seat requested and reconfirmed, fast track arranged where available.
• Cot, high chair, bath support, fridge and steriliser confirmed in writing with the hotel.
• Established formula and home weaning foods carried from India; nappies and toiletries bought locally.
• Nearest paediatric hospital identified and route timed; insurance checked for outpatient cover.
• Mosquito net for the cot in the wet season, and a plan that keeps the baby indoors from eleven to four.

Hospital departments, hotel equipment and airline bassinet policies all change, and health guidance including mosquito-borne disease advice is updated regularly. Confirm current details with the hospital, hotel and airline directly, check your paediatrician's advice before travel, and verify entry and TDAC requirements with the Thai Immigration Bureau.
