Baby products sold on popular online marketplaces risk choking and suffocating young children, experts have warned.Which? said it has identified 150 potentially lethal products being sold to UK consumers on Amazon, Etsy, eBay and TikTok shop.These include self–feeding products that enable babies to bottle feed with little to no assistance, with some fastening around their neck.It also found sleeping bags that cover a child's face and animal–shaped sleeping pillows that can cause suffocation and overheating.Experts said they don't believe the products meet safety standards, with these categories triggering several alerts and safety notices from the Office for Product Safety and Standards (OPSS).Sue Davies, Which? Head of Consumer Protection Policy, said: 'The lives of babies are at risk because these platforms won't stop dangerous products from reaching their customers – even though they are well aware that these products can be deadly.'Which? has shown how easy it is to find these unsafe products with simple tools, so it's impossible for us to take companies as powerful as Amazon or eBay at their word when they claim safety is a top priority.'Lives will be at risk until online marketplaces are finally forced to clean up their act.' One knitted sleeping bag on Etsy had a hood and no arm holes and was shown covering a baby's mouth and nose Self–feeding products create a serious risk of harm or death from choking on the feed or aspiration pneumonia, which is when the feed gets into the baby's lungsThe team at Which? said they had little difficulty finding 150 examples of products that could end a baby's life using simple key word searches on popular online sites.It found 54 baby self–feeders for sale across Alibaba, Amazon, eBay, OnBuy and TikTok Shop.These products create a serious risk of harm or death from choking on milk or formula, or aspiration pneumonia – which is when feed gets into the baby's lungs.This is because babies do not have the dexterity or cognitive ability to control the flow of the feed or to know when to stop.The process of choking is silent, since the airway is blocked, so even a nearby parent may not realise this is happening.Which? discovered 59 sleeping bags for sale on online marketplaces including Alibaba, AliExpress, Amazon, eBay, Etsy and Wish that they believe to be unsafe due to serious risk of suffocation.The sleeping bags include hoods which could cover a baby's head and face or lack arm holes, or both, meaning a sleeping infant could slip down inside.One knitted sleeping bag on Etsy had a hood and no arm holes and was shown covering a baby's mouth and nose.

The experts warned products such as these put the lives of babies at risk, and argued that online marketplaces need to 'clean up their act'Which? believes that online marketplaces will not take meaningful action to protect their customers unless they are compelled to do so by law and face significant fines for breaking the rules.This means that online marketplaces must be given clear responsibilities for ensuring the safety of products that they list on their sites, it said.The Product Regulation and Metrology Act, adopted in July last year, enables the Secretary of State to impose product safety requirements on online marketplaces.However, Which? argues this has been delayed and the government has only recently consulted on possible changes.Alibaba.com, AliExpress, Amazon, eBay, Etsy, OnBuy and TikTok Shop all said they take product safety seriously and removed the items flagged by Which?, with several saying they had already removed some listings or acted quickly after being alerted.The companies said they have policies, monitoring systems and seller requirements in place to prevent unsafe products being sold, and many pledged to strengthen their controls.Wish did not respond to requests for comment. How to shop safely for babycare products Sleeping bagsAny item marketed as a sleeping bag for babies which includes a hood is unsafe and should not be sold.Avoid baby sleeping bags with hoods or excess material, such as large bows or other novelty additions. These risk covering a baby's head and face while they move around in their sleep.Always use a sleeping bag with arm holes as these help to stop babies slipping down inside the bag. The Lullaby Trust, a charity which aims to reduce unexpected death in infancy, strongly advises against letting babies sleep in products that restrict their movement or position them in a way that could block their airway.Other things to avoid include products sold as multipurpose items – e.g., a swaddle, a stroller cover, and a baby cocoon as well as a sleeping bag. Baby sleeping bags have to conform to strict standards.Self–feeding productsAny 'self–feeding' product for babies and infants can be lethal and should be avoided. Sleep pillows'Baby Sleep Pillows' should not be used for babies under 12 months old.Do not place a 'Baby Sleep Pillow' in a cot or crib.Always follow NHS safe sleep advice.
