Transitional Swaddle Sack – Better Sleep, Safer Sleep for Your Little One
Give your baby the comfort and security they need with our Transitional Swaddle Sack (TSS), designed to promote better sleep and safer sleep. Perfect for babies who love sleeping with their arms up, are learning to roll over, or self-soothe by sucking on their hands, this innovative swaddle sack is the ideal solution for transitioning out of a traditional swaddle.
The unique half-length sleeves with fold-over mitten cuffs gently suppress the Moro (startle) reflex, helping your baby sleep longer and more soundly. Unlike restrictive swaddles, our design allows babies to move their arms freely if they roll over, ensuring safer sleep while still providing a cozy, secure feel. Recognized by the IHDI as Hip Healthy, this swaddle supports your baby’s natural position without restricting movement.
Designed by a nurse with your baby’s best interest in mind, the TSS features:
✔️ Fold-over mitten cuffs (open or closed) for self-soothing or scratch protection
✔️ Soft, stretchy 100% cotton fabric (TOG 0.5) for breathable comfort
✔️ Two-way double-pull zipper for hassle-free diaper changes
✔️ Three sizes (S/M/L) based on weight for a perfect fit
Now available at an unbeatable price of just $18.30 (originally $23.99), this patented swaddle sack is the safest and easiest way to transition your baby from a full swaddle to more independent sleep. Machine washable and durable, it’s a must-have for every parent prioritizing safety and comfort.
Upgrade your baby’s sleep routine today—because better rest means happier days!
