Few things are more comforting than a cozy pair of pajamas. I remember buying my son’s first cotton onesies. We lived in Hong Kong at the time and while the synthetic pajamas available there weren’t treated for flammability as they were required to back home in the United States, I didn’t like the clammy handfeel– I thought he would be more comfortable in cotton. When he was small, he brightened every day when I came home from work. He’d have his bath and put on his jammies, and we would nestle together and read “Goodnight Moon” over and over. Twenty-two years later, those onesies are still packed away in a plastic bin in the basement. I can’t bear to give them away and hope that one day a grandchild will wear them.

Since the mid-seventies, children’s sleepwear sold in the U.S. has had to adhere to strict flammability-resistant standards. At my house, we are extremely sensitive to this issue because we have spent many many days at Shriners Hospital for Children for treatments for a burn injury our daughter suffered as an infant. We have seen first-hand the pain, disability, and disfigurement caused by this type of injury – both hers and other children’s. We are extremely grateful that Shriners Hospital provides treatment at no cost to hundreds of children each year.

The first flame-retardants used in children’s sleepwear were applied to  the finished garments, which were often treated with a chemical known as Tris, a known carcinogen. Tris was banned from children’s clothing in 1977, however it is still used as a flame retardant in many children’s toys and accessories. In the past year, New York, Maryland, and Vermont have banned Tris from being used in some children’s products. A while back, we discussed toxic chemicals in our kids’ clothing and what we can do about it. Most synthetic children’s sleepwear today is made with “naturally” flame-resistant polyester. However, even polyester sleepwear has a treatment; most likely the polyester fibers were chemically bonded with a flame-retardant chemical (this makes sense since polyester is naturally flammable). This treatment can not be washed out of the garment because it is bonded with the fibers which also means it is more stable and less likely to off-gas or transfer to your child’s skin. But the chemical is still being used, just earlier in the process, which means there are effluents and workers are potentially exposed.

If you would like to avoid all chemicals in your children’s sleepwear, then the answer is 100%-organic cotton. We now know just how great the amount of pesticides are used in the production of cotton, and the benefits of organic cotton for our kids and the environment. Organic cotton is ideally suited for sleepwear because comfy, soft, and pesticide-free. Nothing will feel as wonderful against your child’s skin and cotton provides excellent warmth and durability. Pajamas made with cotton are not required to have any flame retardant treatment as long as they are recommended to be worn close to the body. Cotton pajamas are required to carry a yellow warning label such as this one:

Sleepwear - WARNING LABEL 1


Snug-fitting pajamas eliminate a layer of air between your child and the jammies. The oxygen in the air can accelerate the flammability and increase the risk to your child so it’s a good idea to follow this warning.

Lucky & Me will be introducing 100%-organic cotton pajamas in the fall. They are a natural extension of the Lucky & Me brand and many customers have been asking for them. In addition to the soft Comfy Ever After fabric, Lucky & Me pajamas will have flatlock seams to ensure snug comfort. Flatlock seams are used by the best underwear and active garment brands.

There are many different methods for conventional seams, where two layers of fabric are overlapped before the seam is sewn, often by an overlock machine. Overlock seams are troublesome because the excess fabric can chafe against the skin.

In flatlock seams, the two layers are trimmed and butt up against each other, then sewn with a multi-needle coverstitch which ensures a flat, smooth join of the fabric. You can see an example of flatlock seaming here:

The single layer and flat seaming prevents chafing and provides a smooth finish against the skin. This is especially important in garments worn snug against our children’s soft skin. And if your children are like mine, they tend to move around a lot during their sleep. Lucky & Me’s flatlock seams will ensure chafe-free comfort all night long. Check out the video below for a tutorial on the benefits of flatlock seams.
