Magnetic baby clothing can feel like a modern miracle during diaper changes—until the questions start: Could a magnet come loose? What about pacemakers? Are magnetic fields harmful? This article breaks down the most common concerns with clear, evidence-based context and practical safety guidance.
The quick answer
Magnetic closures can be used safely in baby clothing when they’re engineered correctly (securely enclosed, tamper-resistant, and compliant with U.S. children’s product safety requirements). The key is construction + testing + common-sense use.
1) Worried about your baby swallowing magnets?
This is the #1 fear—and it’s a fair one, because loose magnets can be extremely dangerous if swallowed, especially if more than one is ingested. The U.S. Consumer Product Safety Commission warns that when multiple magnets are swallowed, they can attract each other internally and cause severe injuries that may require surgery.

What makes Magnetic Onesie different: our magnetic fasteners are securely sewn and fully encased within multiple layers of fabric. They’re designed to be inaccessible to babies and toddlers, and would require tools like scissors or a seam ripper to expose (not something a child can do).
Tested for peace of mind: our garments undergo independent testing and are designed to be CPSC-compliant with applicable U.S. children’s product safety requirements.
-
Stop using the garment if it becomes damaged or a seam opens.
-
If magnet ingestion is ever suspected, seek immediate medical care (this is standard CPSC guidance). (U.S. Consumer Product Safety Commission)
2) Concerned about magnets near your baby’s heart?
Parents often worry that magnets near the chest could affect the heart or general health.
What major health guidance says: the World Health Organization’s review of static electric and magnetic fields concluded that no evidence of adverse health effects has been noted in the scientific literature beyond certain perception-related effects under specific conditions. (Inchem)
-
Magnetic closures in garments involve static magnetic fields not radiation.
-
Everyday exposures to static fields at typical consumer levels are not associated with confirmed health harms in the WHO’s assessment.
3) Worried about “magnetic fields causing harm”?
It helps to ground this in widely used international safety guidelines.
The International Commission on Non-Ionizing Radiation Protection (ICNIRP) publishes exposure guidelines designed to protect against established effects. Their materials explain that very high static magnetic fields (well beyond everyday consumer contexts) are where temporary sensory effects like vertigo can occur. (ICNIRP)
The kinds of “very high field” scenarios discussed in these guidelines are typically associated with specialized environments (e.g., certain industrial or medical settings), not ordinary baby apparel use. (ICNIRP)
4) Concerned about magnets affecting pacemakers or ICDs?
This is an important nuance: the concern is usually not for the baby, but for a parent/caregiver with an implanted device.
The American Heart Association notes that magnets in everyday items (they specifically mention things like headphones) can interfere with pacemakers/ICDs if kept close, and advises keeping magnets at least 6 inches away from the device. (www.heart.org)
The FDA similarly recommends keeping consumer electronics that may create magnetic interference at least 6 inches away from implanted medical devices. (U.S. Food and Drug Administration)
-
“If you or a caregiver has a pacemaker/ICD, follow your clinician’s guidance and keep magnetic closures away from the implant site (commonly advised: 6 inches).” (www.heart.org)
-
“When in doubt, ask your cardiologist—especially if you routinely hold baby against your chest near the device.”
5) Worried about lead in baby clothing?
Parents sometimes assume magnets “attract lead,” but lead isn’t “pulled” out of fabric by magnets in any meaningful way—lead concerns in children’s products are addressed through materials selection and compliance testing, not magnetism.
In the U.S., children’s products must meet strict limits for lead in accessible components (commonly referenced at 100 ppm for total lead content, with additional rules for lead in surface coatings). (U.S. Consumer Product Safety Commission)
Our garments are independently tested to meet applicable U.S. children’s product safety requirements, including lead limits. In addition, our ROMAG fasteners are OEKO-TEX® certified—meaning they’re tested against a list of harmful substances—while our fabrics are 100% natural, GOTS-certified organic cotton.
6) Worried about skin irritation from magnets?
A well-designed magnetic garment keeps magnets fully shielded from direct skin contact—they’re enclosed within fabric layers.
At Magnetic Onesie, magnets are hidden between layers of fabric, and baby’s skin touches only soft, breathable organic cotton.”
Your child’s safety is our top priority.
Our magnetic closures are designed to be secure and inaccessible to little hands. We also recommend simple, common-sense use: inspect garments regularly, discontinue use if a seam is damaged, and keep magnetic closures away from implanted medical devices (as advised by the AHA/FDA—typically 6 inches).
