Preparing for a new baby is expensive. Prams, cots, car seats, bouncers, monitors — the costs add up quickly, and it is entirely understandable that families look to buy second-hand wherever possible. The good news is that many baby items can be purchased safely from charity shops, online marketplaces, and friends. The bad news is that some items carry very real safety risks when bought used, and being unable to verify their history can put your baby in danger.
This guide explains which categories are fine to buy second-hand, which to approach with caution, and which you should always buy new — along with the reasons why.
Baby clothing is one of the safest and most sensible things to buy second-hand. Babies outgrow clothing so rapidly — sometimes within weeks — that second-hand items are often barely worn. As long as garments are washed at the correct temperature before use and checked for any loose buttons, frayed drawstrings, or broken fastenings, they present no elevated safety concern. UK charity shops are an excellent source.
One thing to check: if buying clothing with any kind of hood or drawstring, ensure the drawstring cannot form a loop. This is a choking and strangulation hazard. UK safety standards since 1994 have prohibited drawstrings on children's garments, but older items may still carry them.
Most hard plastic and wooden toys can be bought second-hand provided they are in good condition. Before using any second-hand toy, check it against the RAPEX or OPSS product safety recall databases to ensure it has not been recalled. Clean surfaces thoroughly. Look for the CE or UKCA marking, which indicates the toy met safety standards at the time of manufacture.
Be more cautious with soft toys if the baby is very young. The NHS advises keeping soft toys out of the sleep environment for babies under 12 months due to suffocation risk. Soft toys bought second-hand should be machine-washable and washed before use.
Battery-operated toys should be checked to ensure battery compartments close securely and cannot be opened by the child.
Baby bouncers and rockers are often in very good condition second-hand because babies use them for only a few months. If buying used:
If the model is older or the brand is no longer trading, you may struggle to find replacement parts or verify recall status. This increases risk somewhat.
A second-hand high chair can be safe if it has not been recalled, all harness straps and buckles are intact and functioning, the tray locks securely, and the chair is stable on a flat surface. Avoid any high chair showing signs of structural damage or where components are missing. Again, check for product recalls before use.
Closed-system breast pumps can theoretically be cleaned and reused, but the NHS recommends using your own pump where possible. Open-system pumps should not be shared at all, as milk can enter the motor housing, posing a hygiene risk. If you do buy a second-hand closed-system pump, clean and sterilise all parts that come into contact with milk, and replace tubing and any membranes before first use.
The basket or carrycot body itself is generally fine second-hand. The mattress is the critical element. Mattresses should always be bought new. Research published in the British Medical Journal and guidance from The Lullaby Trust indicates an association between second-hand mattresses and sudden infant death syndrome (SIDS), though causation has not been definitively established. The current guidance from The Lullaby Trust is to use a new, clean, firm, flat, waterproof mattress that fits the sleeping space without gaps at the sides.
This is the most important item on this list. You should never buy a second-hand car seat unless you know with absolute certainty its full history — and even then, most safety experts advise against it.
Here is why. Car seats are designed to absorb the energy of a crash, and doing so can cause internal damage to the plastic shell and harness that is invisible to the naked eye. A seat that has been in a collision — even a minor one — may no longer provide adequate protection, yet look perfectly normal. Sellers may not know the seat was involved in an accident, or may not disclose it.
Additionally:
If budget is a concern, many charities and local councils offer car seat loan schemes. The Good Egg Safety charity and some children's centres can help signpost families to lower-cost new or professionally checked options. Always register your seat with the manufacturer so you are notified of any recalls.
The sleep environment is the highest-risk area for infant death, and the safety of a cot depends heavily on factors you cannot assess on a second-hand purchase:
If you do accept a gifted or second-hand cot from a trusted source, have it checked by someone who knows what to look for, replace the mattress entirely, and check the specific model against current recall databases.
Products such as the Dock-a-Tot or similar infant loungers should not be used for sleep at all, whether new or second-hand. These products are not safety-rated as sleep surfaces and have been linked to infant deaths. They are not recommended by the NHS or The Lullaby Trust for unsupervised sleep.
Buying second-hand is a practical and environmentally responsible choice for many items. The key is knowing which items carry risks that cannot be seen, and choosing to invest in new products where your baby's life depends on it.
