Santa needs to check his list twice to make sure all kids’ toys are safe this holiday. The U.S. Consumer Product Safety Commission’s (CPSC) says there were an estimated 231,700 toy-related injuries treated in emergency rooms in 2023. Additionally, the CPSC received reports of at least 10 toy-related deaths among children aged 14 and younger last year, according to TODAY.

According to NBC News, unintentional injuries are the leading cause of death among children in the U.S., says Dr. Brandon Rozanski, a pediatric resident at Tripler Army Medical Center in Honolulu.

Here are the most dangerous products to avoid:

• Water beads. These tiny, colorful beads expand when wet. Because they look like candy, kids may eat them by mistake. The beads can continue to expand in the body causing pain, vomiting, dehydration or life-threatening injuries warns the CPSC. Some children put them into their ears which can result in damage to the ear and hearing loss. Experts do not recommend allowing kids under the age of five to play with water beads and older children should be supervised.

• Toys with button batteries. These coin-like batteries that are found in many electronic devices, as well as hearing aids, can pose a serious choking hazard. A 2022 study found that the incidence of battery-related emergency room visits more than doubled in the last decade. When a button battery mixes with saliva or moist skin tissue, it triggers an alkaline (chemical) reaction that can burn a child. Once this reaction starts, it literally liquefies and dissolves or burns the skin. Even worse, if the button battery isn’t removed promptly, the reaction can continue after the battery is removed causing severe damage, according to Johns Hopkins Medicine. Experts warn that even used batteries can be hazardous and recommend taking extra precautions with their storage and disposal.

The CPSC issued stringent requirements for the safe packaging of button and coin batteries after Congress passed a bill called Reese’s Law, named after Reese Hamsmith, an 18-month-old child who died after ingesting a button cell battery from a remote control.

• Magnets. Little children love to put small things in their mouths and the popular magnetized toys are no exception.  According to the American Academy of Pediatrics, loose and high-powered magnetic toys pose a health hazard to children. If they are ingested, the magnets can pull together inside your child's digestive system with enough force to cause serious damage. These magnets can also get stuck in the nose and cause serious injuries to the nasal respiratory tract. Safety standards were enforced in 2022 preventing the sales of toy products that contain magnetics small enough to swallow. However, it is advisable to always supervise small children when they are playing with magnetic toys.

• E-scooters. Electric scooters have surged in popularity and so have injuries, says the Children’s Hospital of Philadelphia (CHOP). From 2020 to 2021, researchers found that the number of children and teens injured on electric scooters rose 71%. Emergency departments reported more than 13,500 such injuries over a two-year period, most affecting boys aged 16 to 18, says NBC News.

Head injuries were the most common, and reportedly nearly 67% of children who sustained head injuries were not wearing helmets. Some accidents involved cars, while others occurred when riders hit potholes or uneven ground. Experts suggest that parents buy scooters with sizes and speeds appropriate for their kids.

“If you’re going to have your 15-year-old teenage boy riding it, they don’t need one that goes 65 miles per hour,” noted Dr. J. Todd Lawrence, a pediatric physician at CHOP.

•Trampolines. While kids look like they are jumping for joy on these products, experts warn that trampolines cause a host of injuries including concussions, broken bones and spinal cord injuries. More than 90% of trampoline mishaps involve children between the ages of 5 and 14, says the American Academy of Orthopedic Surgeons. While trampolines enclosed in safety tents are safer, parent should always supervise kids on trampolines and limit the number of kids jumping on the apparatus at once.
