Yes, when they're made and tested specifically for use by children.
Each manufacturing batch of Sleepy Strands bonnets is tested and certified by a third party CPSC-accredited lab. This ensures compliance with children's product safety rules in the US.
Additionally, our silk is OEKO-TEX Made in Green certified. This goes beyond the Standard 100, indicating that a third party certified that our materials were:
1) Safety tested and do not contain harmful substances,
2) Made in environmentally responsible facilities, and
3) Made in socially responsible and safe workplaces.
Finally, we've taken extra precautions in our design compared to other bonnets for kids. Our Safety Loop helps ties stay in place on top of the head instead of around the neck, even for highly active sleepers.
If all else fails and the bonnet still slips forward, the right size bonnet still won't cover a child's face while sleeping.
