SwaddleDesigns Transitional Swaddle Sack - Arms Up Sleeves, 3-6 Months, Heavenly Floral Pink

Meet the SwaddleDesigns Transitional Swaddle Sack

Designed by a nurse to ease the shift from traditional swaddling to a wearable blanket, this sack offers a snug, breathable wrap that remains comfortable as your baby grows. The Heavenly Floral Pink pattern adds a gentle, soothing aesthetic to bedtime rituals.

Arms Up for self soothing and a smoother transition

The transition design features 1/2-length sleeves with foldover mitten cuffs. Closed cuffs provide partial suppression of the Startle Reflex, helping baby settle more easily, while keeping arms in a snug position. When cuffs are opened, tiny hands become available for self soothing and exploration. This balance is ideal for babies who prefer to sleep with arms up or who are starting to roll.

Safety note: if baby rolls onto the tummy, the arms remain free enough to assist breathing while staying securely swaddled in a wearable blanket.

Ease of use and diaper changes

The 2-way zipper zips down from the top for easy placement and zips up from the bottom for quick diaper changes. This feature minimizes disruption during late-night changes and keeps baby cozy throughout the process.

Fit, fabric, and care

Made from 100% cotton with a TOG 0.5, the Transitional Swaddle Sack delivers soft stretch and breathable comfort. Its hip healthy design supports a natural, flexed leg position as babies grow, reducing resistance during sleep. It is machine washable and designed for long-lasting wear.

Who it’s for and real-life use

Ideal for babies who prefer arms up, those who are starting to rollover, or infants who outgrow traditional swaddles. The 1/2-length sleeves with foldover cuffs create a snug, secure feel while still offering freedom when needed. Whether used for nighttime sleep or daytime naps, this wearable blanket provides a gentle transition from swaddling to a sleep sack.
