  • Care Instructions

    Swaddelini is ready to use right out of the packaging and easy to care for.

    ⭐ May work better with diaper flap facing down (brand tag facing up)

    ⭐ May work with PJs, or onesie/pants combo, or just a diaper and socks underneath.

    ⭐ Swaddelini Original should be washed on cold and tumble dried on low. If it shrinks, give it a good stretch back to its original size. 

    ⭐ The Swaddelini Bamboo can be washed and dried with heat.

  • Recommended Sizing

    The Swaddelini small size goes from about 6-12 pounds. The large goes from 12 pounds up to 18 pounds and both can be used as a transition swaddle. When the baby rolls over, leave arms out! This makes the Swaddelini a wearable blanket.

  • Baby Shower Gift

    If you are buying this for a baby who is yet to be born, I highly recommend the small size even if you are told they are going to have a big baby.

  • Special Customizations
