Kids’ pajama labels can be surprisingly confusing. You might see phrases like snug-fitting, not flame resistant, flame retardant, or keep away from fire, depending on where you live and where the pajamas are sold. Canada, the United States and Great Britain each approach children’s sleepwear safety a little differently. Here’s what those differences actually mean when you’re shopping.

Do All Kids’ Pajamas Have to Be Flame Resistant?
Not necessarily. Children’s sleepwear has to meet the safety requirements of the country where it’s sold, but that doesn’t always mean the pajamas themselves will be labelled flame resistant.
Fit, fabric, construction and the type of sleepwear can all affect which requirements apply. That’s why two perfectly compliant pairs of pajamas can have very different labels.
Canada, the U.S. and Great Britain Don’t Use One Universal System
The wording on children’s sleepwear can change depending on where the garment is sold. Reading each market in its own context makes the labels much easier to understand.
Canada
In Canada, both close-fitting and looser children’s sleepwear have flammability requirements, although different standards can apply depending on the style.
That doesn’t mean every pair has been treated with flame-retardant chemicals. Health Canada specifically notes that children’s sleepwear can meet the requirements without them. Choose the appropriate size and follow the fit and care instructions.
What Does “Wear Snug-Fitting, Not Flame Resistant” Mean?
If you’ve bought kids’ pajamas in the United States, you may have seen the wording “WEAR SNUG-FITTING, NOT FLAME RESISTANT.” It means exactly what it says: the pajamas are designed to fit close to the body and should not be considered flame resistant.
That close fit is intentional, so avoid sizing up simply to make snug-fit pajamas feel loose. Choose the appropriate size and follow the fit guidance for the garment.
Why Do UK Pajamas Say “Keep Away From Fire”?
In Great Britain, children’s nightwear follows a different system from the U.S., so parents shouldn’t expect to see the same snug-fit wording. Depending on the type of nightwear and how it performs, a garment may carry wording such as:
- KEEP AWAY FROM FIRE — a fire-safety warning used on certain children’s nightwear
- LOW FLAMMABILITY TO BS 5722 — wording that may appear depending on the type of nightwear and how it performs
A “KEEP AWAY FROM FIRE” label does not mean the pajamas are defective or unsafe to sell. It’s part of the fire-safety labelling system used for certain types of nightwear.
Does Flame Resistant Mean the Pajamas Were Chemically Treated?
Not automatically. “Flame resistant” describes how a garment performs, not necessarily how that performance was achieved. Different fabrics, constructions and treatments can all play a role.
Across Canada, the U.S. and Great Britain, you shouldn’t assume that a fire-safety label automatically means chemical flame retardants were used. If that’s something you specifically want to know about a pair of pajamas, check the product information or ask the manufacturer.
What Parents Should Check
You don’t need to memorize the regulations. A few simple habits go a long way: focus on the specific garment, the intended fit and the information provided with it rather than trying to decode every regulation behind the label.
Choose Sleepwear
Choose pajamas made and sold as sleepwear.
Follow the Fit
If they’re designed to be snug, don’t deliberately size up to make them loose.
Read in Context
Safety wording can mean different things depending on the country.
Check Care
Washing and drying can affect fit and, for some garments, performance.
Check the Pair
Fabric alone doesn’t tell you everything about how pajamas meet sleepwear requirements.
The Bottom Line: Know What the Label Is Asking You to Do
Kids’ pajamas don’t all follow the same safety rules or carry the same labels. What matters most is choosing sleepwear intended for your child, selecting the proper fit, and following the safety and care information provided with the garment.
You don’t need to decode every regulation behind the label. You just need to know what the label is asking you to do.
Kids’ Pajama Safety Labels, Explained
Are all kids’ pajamas flame resistant?No. Kids’ sleepwear can follow different safety requirements depending on where it’s sold, so not every pair will be labelled or described as flame resistant.
Are Canadian snug-fit pajama rules the same as U.S. snug-fit rules?No. Both countries have safety requirements for children’s sleepwear, but they approach snug-fitting pajamas differently. That’s why labels and fit guidance can vary between markets.
Why do U.S. kids’ pajamas say “not flame resistant”?Some snug-fitting pajamas sold in the U.S. carry the label “WEAR SNUG-FITTING, NOT FLAME RESISTANT.” It means the close fit is intentional and the pajamas should be worn according to their intended sizing.
Why do UK children’s pajamas say “keep away from fire”?“KEEP AWAY FROM FIRE” is a fire-safety warning used on certain children’s nightwear in Great Britain. Seeing it on a label does not automatically mean there is something wrong with the garment.
Do flame-resistant pajamas always contain flame-retardant chemicals?No. Flame-resistant performance can be achieved in different ways, so you shouldn’t assume a chemical treatment has been used based on the label alone. Check the information for the specific product if this is important to you.
Can 100% cotton be used for children’s pajamas?Yes. Cotton is commonly used in children’s sleepwear, but the fit, construction and safety requirements can vary depending on the product and where it’s sold. Always follow the garment’s fit and safety information.
Why can the same type of pajamas have different labels in different countries?Children’s sleepwear rules vary between Canada, the U.S. and Great Britain. As a result, pajamas sold in different markets may use different safety wording or fit guidance. When shopping online, use the product information provided for your country.
