Do I need to bring a car seat?

If you are strictly using private airport transfers and GrabFamily, you don't necessarily need one, but for peace of mind and safety on rural roads, bring a lightweight travel car seat.

Is the tap water safe for children?

No. Use bottled water for everything, including brushing teeth. 7-Eleven stocks large bottles everywhere.

Traveling Thailand with young children

Thailand is incredibly family-friendly if you minimize transit times and stick to established tourist hubs like Chiang Mai or Koh Samui. Prioritize private transfers over public buses and always book accommodation with a pool to ensure daily downtime during the hottest part of the day.

Choose your base wisely. Avoid 'island hopping' every 2 days. Pick one base (like a resort in Phuket or a villa in Koh Samui) and stay for at least 5-7 days. Constant travel with young children leads to burnout.
Use Grab for all ground transport. Download the Grab app immediately. It is the Southeast Asian equivalent of Uber. You can select 'GrabFamily' vehicles which come pre-equipped with a child safety seat, avoiding the need to carry your own.
Manage the heat. Structure your day to be indoors or in a pool between 1:00 PM and 4:00 PM. The humidity is intense, and this break prevents heat exhaustion and mid-afternoon meltdowns.
Strategic food planning. Most Thai restaurants will cook 'no spice' versions of dishes for kids upon request. Carry your own supply of familiar snacks from 7-Eleven, which is ubiquitous and carries reliable international brands.
