Amazing Baby Transitional Swaddle Sack – Arms Up Sleeves, 6-9 mo, Lrg, Sterling Tiny Elephants

Calm, safe, and simple: the Amazing Baby Transitional Swaddle Sack

The Transitional Swaddle Sack is designed to gently ease your baby from a traditional swaddle into a wearable blanket. With arms up half-length sleeves, it supports a cozy, secure feel while allowing natural movement as little ones begin to explore rolling and self-soothing. The design emphasizes comfort and practicality for sleepy hands and curious minds alike.

Key benefits at a glance

• Arms-up posture supports a comforting sleep-ready stance for babies who prefer this position.
• Unique 1/2-length sleeves with foldover mitten cuffs deliver gentle suppression of the Moro reflex when cuffs are closed, helping calmer sleep.
• If baby rolls over, the sleeves permit arm movement so they can reposition and access air for safer sleep.
• Foldover mitten cuffs can be opened or closed to support self-soothing by hand, or to protect against facial scratches.

How it works in real life

Ideal for bedtime routines, daytime naps, or travel, this wearable blanket grows with baby through a key transition: it’s perfect for babies who like to sleep with arms up, are starting to roll, or prefer hands-in-mouth soothing when swaddles end. It blends the security of a swaddle with the flexibility of a sleep sack.

Fabric, warmth, and care

• Crafted from 100% cotton for a soft, stretchy, breathable feel during naps and nighttime.
• 0.5 TOG provides moderate warmth, suitable for a range of room temperatures. Layer with a bodysuit or a sleeveless wearable blanket in cooler settings.
• Care is simple: machine wash warm and tumble dry low.

Safety and design cred

Recognized by the International Hip Dysplasia Institute as hip-healthy, the sack was designed by a nurse with your baby’s comfort in mind. US patents and other international protections reflect the thoughtful construction of this wearable solution.

Fit, size, and color

For babies around 6–9 months and weighing about 21–24 lb, the Lrg size fits well. The Sterling Tiny Elephants print adds a playful, everyday touch to your baby’s sleepwear.

• You may enjoy calmer bedtimes as your baby learns to self-soothe within a cozy, secure layer.
