SwaddleDesigns Organic Transitional Swaddle Sack – Arms Up Sleeves, Small 0–3M

Soft, safe, and adaptable sleep transition

The Organic Transitional Swaddle Sack from SwaddleDesigns is designed to ease your baby from a full arm-restraining swaddle to a more flexible sleep arrangement. The arms-up design invites self-soothing while keeping little arms close in a secure, flexed posture that feels familiar and reassuring.

Crafted from 100% organic cotton with GOTS certification, this sleep sack offers a soft, breathable touch that moving newborns appreciate. With a TOG of 0.5, it suits moderate room temperatures, and layering with a bodysuit or a lightweight wearable blanket can help when nights turn cooler.

Key design features that matter

• Arms Up ½-length sleeves with foldover mitten cuffs provide adjustable self-soothing and protection from facial scratches.
• Partial suppression of the Moro reflex helps baby settle while allowing air access if the baby rolls onto a tummy.
• Two-way zipper with a guard makes it easy to dress and change diapers without irritating delicate skin.
• 100% Organic Cotton, GOTS certified for soft, breathable daily wear.
• IDHI Hip Healthy recognition signals a hip-friendly design for growing hips.
• Designed by a nurse and protected by US patents 11,812,795 and D833,613 for thoughtful safety features.

Who this transitional sack fits today

• Ideal for babies who sleep with arms up or who are starting to roll over, offering continued comfort and positioning.
• Great for babies who like to suck on their hands to self-soothe or who outgrow classic swaddles.
• Supports a gentle, flexed posture without constricting movement, helping little ones explore new sleep habits safely.

Care and use tips: choose the size by weight (Small = 6–14 lbs, 0–3 months). The sack is machine washable warm and tumble dry low, designed for regular laundry days. The fabric’s breathability helps reduce overheating while maintaining warmth where needed.

Because SwaddleDesigns is designed by a nurse, this sack emphasizes both comfort and practical features for busy families. It’s not a wrap, but a transitional tool meant to support your baby’s evolving sleep preferences with a secure, flexible approach.
