Do baby sleepwear fabrics contain toxic flame retardants?
Many flame retardants used in consumer goods are linked to serious health issues in children, including developmental and cognitive concerns, according to peer-reviewed research.
What's actually in it
Baby sleepwear and other household items often contain halogenated flame retardants and organophosphate ester flame retardants. These chemicals are added to materials to slow down fire, but they don't stay put. They shed from fabrics and accumulate in house dust, where children can breathe them in or ingest them through hand-to-mouth contact.
These substances are not just inert additives. They are active chemicals that can interfere with a child's health from the prenatal stage through their developmental years.
What the research says
The science is clear that these chemicals pose risks to growing children. A 2026 study in Environ Pollut found that prenatal exposure to organophosphate ester flame retardants is linked to changes in child cognition. Another 2026 study in Environ Res connected gestational exposure to these same chemicals to shifts in child growth, specifically affecting weight, height, and body mass index between the ages of 2 and 10.
The impact extends to behavioral and physical health as well. A 2026 study in J Expo Sci Environ Epidemiol identified links between these flame retardants in house dust and outcomes on the Child Behavior Checklist. Furthermore, a 2026 study in Environ Res found that halogenated flame retardants are associated with thyroid function changes and ADHD-related traits in children.
Finally, allergies are a growing concern. A 2026 study in Sci Total Environ established a clear association between exposure to brominated flame retardants and the diagnosis or symptoms of allergies in a nationally representative sample of children in the US.
