Trois Kilos Sept has been caring for babies since 2012.

Trois Kilos Sept isn’t just the average weight of a baby at birth; it’s also the beginning of the most beautiful adventure: becoming a parent.

Trois Kilos Sept is the weight of love, of those first cuddles with your baby, and of the incredible vulnerability we’ve all felt on becoming parents.

Designed in Savoie, Trois Kilos Sept products are made to accompany your baby with style and a gentle touch. Each collection is a haven of softness and tenderness, where timeless design meets thoughtfully chosen materials.

Because the first days, weeks and months are treasures we hold onto for life, we’re here for you.

Every First Moment. That’s our commitment: to be a quiet but essential companion through every new milestone, every first burst of laughter and every peaceful night.

Learn more about the baby brand Trois Kilos Sept

At Trois Kilos Sept, we’re deeply committed to the safety and well-being of babies and newborns. Every product is carefully designed, the result of hours of research, testing and meticulous refinement. 

Compliance with NF EN 16781 standards
One of the most important features of a sleep sack is the size of its neck opening. It must be designed to prevent the baby from slipping down inside the sleep sack, which could pose a suffocation risk. That’s why every sleep sack is tested to ensure it’s easy to put on and take off while staying securely in place once fitted.

Quality Materials
Little ones have delicate skin, and at Trois Kilos Sept, we make sure every material is soft, breathable and, above all, harmless. Our products are tested to ensure they’re free from toxic or irritating substances, helping keep your baby safe.

Plush Toy Safety

Because they’re often our babies’ first friends, they must be safe. That’s why we make sure our plush toys don’t shed easily, helping prevent any risk of swallowing loose fibers. We test every part to ensure it can’t be pulled off.

Safer Toys for Babies

Babies explore the world with their mouths, so it’s important to make sure every toy is free of small parts they could swallow. Our toys undergo pull tests to ensure nothing comes loose, even after hours of play.

Certified Testing

All our tests are conducted in accordance with the strictest international standards for baby products. Our testing is carried out by independent laboratories.
