When to use Thule Infant Sling or Baby Supporter – main differences

Use Infant Sling for younger babies who cannot sit, and Baby Supporter for babies who can sit upright independently.

The main difference between the Thule Infant Sling and Baby Supporter is your child’s age and ability to sit upright.

  • Infant Sling (1–10 months):
    Designed for babies who cannot sit independently. It provides a reclined, hammock-like position with maximum support and stability.

    There are two versions depending on your trailer model:

  • Baby Supporter (6–18 months):
    Designed for babies who can sit upright on their own. It offers a more upright seating position with padded sides and head support.

👉 If your baby cannot sit steadily → choose Infant Sling
👉 If your baby can sit upright → choose Baby Supporter

In the overlap period (6–10 months), the choice depends on your child’s development and stability.
