Buying and Selling Used Baby and Kids' Gear in Thailand
Baby gear is the best value category in the second-hand market, because children outgrow most items within months. But a few items affect safety directly and should never be bought used. This guide separates what is safe, what needs careful inspection, and what you should buy new.

Safe to buy second-hand
- Children's clothes: outgrown in months, often nearly new — a hot wash and a day in the sun is enough.
- Picture books, wooden toys and hard plastic building blocks: easy to clean and they barely degrade.
- Strollers, bouncers and high chairs: check the frame and every harness strap and they last for years.
- Breast pump motor units: the motor itself is fine used, but buy every part that touches milk brand new.
Do not buy second-hand
A car seat with unknown history is the number one thing to avoid. Even a minor crash creates invisible stress fractures inside the plastic shell, and the seat will not protect a child in the next impact. If you do buy used, buy from someone you know who can confirm it has never been in an accident.
The same applies to children's helmets: the impact foam is single-use and degrades with age. Used infant mattresses are also risky because uneven softening affects safe sleep directly — buy those new.
Pacifiers, bottles, teethers and anything that regularly goes in a child's mouth should always be new. Rubber and plastic degrade through repeated sterilising, and micro-scratches harbour bacteria.
Car seats: what to check if you buy one anyway
- Find the manufacture and expiry date on the sticker under the base or on the side. Most seats last 6-10 years from manufacture, and Thailand's heat ages plastic faster than cooler climates.
- Get the model and standard number (for example ECE R44/04 or R129 i-Size) and search whether that model was ever recalled.
- Check that the harness webbing is not frayed, that the buckle clicks crisply, and that the internal foam has no permanent dents.
- Ask for the manual or find it online to confirm it installs correctly in your own car, with both a seat belt and ISOFIX.
Cleaning before use and before selling
Most stroller fabrics and high-chair seat pads are removable. Wash them with a fragrance-free baby detergent and dry them in strong sunlight to kill dust mites and remove the musty smell that items stored in humid air-conditioned rooms in Thailand usually pick up.
Wipe metal frames and wheels with mild soapy water and check the folding joints for rust. If there is flaking rust, say so plainly in the listing — sellers who state flaws upfront sell faster and get haggled less.
Soak plastic toys in a vinegar solution or a child-safe disinfectant, rinse and dry completely. Always remove batteries before shipping a toy.
Pricing and photos that sell fast
Brands Thai parents recognise — popular stroller and car seat brands — typically resell for 40-60% of retail in good condition with the original box. Clothes almost always sell better as multi-item bundles than individually.
Photograph in daylight near a window and show the whole item, every flaw, the manufacture-date sticker and all included accessories. State the suitable age, the weight limit and why you are selling (usually: outgrown). That detail builds trust much faster than a lower price.
