Trois Kilos Sept - Every first moment

Trois Kilos Sept, a French company based in Savoie, specializes in baby care essentials and supports your babies from 0 to 24 months. 

From footed sleep sacks and sleeping bags, to bath and mealtime essentials, you will also find baby bedding (sleeping bags for every season, cot bumpers, bed canopy & mosquito net, etc.) as well as developmental toys for magical moments with baby.

Find all the little essentials to dress your newborn, at the maternity ward and for their first nights, such as the newborn kit, baby pajamas, front-opening bodysuit, baby brassiere and matching little accessories.

Since 2012, Trois Kilos Sept has been pampering babies.

Trois Kilos Sept is not just the average weight of a baby at birth — it is also the starting point of the most beautiful adventure: becoming a parent.

Trois Kilos Sept is the weight of love, of the first embraces with baby and of that incredible vulnerability we all felt when becoming parents.

Designed in Savoie, Trois Kilos Sept products are crafted to accompany baby with style and delicacy. Each collection is a haven of absolute softness and tenderness where timeless design meets the gentleness of the materials.

Because the first days, the first weeks and the first months are all treasures we keep for life, we are here.

Every First Moment. It is our commitment: to be the discreet yet essential companion for every new milestone, every first burst of laughter and every peaceful night.

Learn more about the Trois Kilos Sept baby brand

At Trois Kilos Sept, there is a deep commitment 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 points for sleeping bags is the neck opening dimension. It is essential that it be designed to prevent any risk of suffocation or submarining, to avoid the baby slipping down inside the sleeping bag. That is why every sleeping bag is tested to ensure it is easy to put on and take off, while staying securely in place once adjusted.


Quality of Materials
Babies have delicate skin, and at Trois Kilos Sept, we ensure that every material is soft, breathable and, above all, non-harmful. Our products are tested to ensure they are free from toxic or irritating substances, guaranteeing your baby's safety.

The Safety of Soft Toys

Because they are often our babies' first friends, it is essential that they be safe. We therefore ensure that our soft toys do not shed their fibers easily, thus avoiding any risk of ingestion. We test every element to make sure it cannot be pulled off.


Baby Toys, Risk-Free

Babies explore the world with their mouths, which is why it is so important to ensure that every toy is free from small parts that could be swallowed. Our toys undergo pull tests to guarantee that nothing comes off, even after hours of play.


Certified Tests

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

Les P'tits Bobos

Les P'tits Bobos are products that meet current standards, but that have little imperfections... a loose seam, a missing snap, or a cosmetic defect, etc.

To avoid throwing them away, we offer these products as "Little Boo-Boos at bargain prices".
