In concrete terms:

  • The buttocks should be lower than the knees .

3. A well-rounded and supported back

The baby's back should be able to curl naturally , especially during the first few months.

💡 Ideally, the baby carrier is made of baby sling fabric .

For what ?

  • This type of fabric is flexible yet supportive .

  • It perfectly conforms to the natural curve of the back.

  • It avoids placing the baby in a position that is too upright.

A well-treated back is like a baby:

The little extras that make all the difference

🌿 Favor natural materials

The baby spends a lot of time against the fabric… and often puts it in their mouth .

Therefore, it is strongly recommended to choose:

  • cotton,

  • flax,

  • or other natural fibers.

🚫 Avoid polyester as much as possible:

  • less breathable

  • less pleasant for the skin,

  • less suitable for prolonged use.

🎒 Ergonomic straps that cross in the back

The shoulder straps play a key role in the wearer's comfort.

Preferred option:

  • Straps that cross in the back for better weight distribution,

  • a shape that's not too curved , to remain comfortable without being rigid.

  • a good balance between flexibility and support.

This allows:

  • to reduce tension in the shoulders and back,

  • to wear for longer periods without discomfort,

  • improved adaptability to different body shapes.
