Description
• Designed by a nurse with 1/2 length arms-up sleeves and fold-over mitten cuffs that can be worn open or closed
• Closed mitten cuffs provide partial suppression of the Moro (startle) reflex while allowing arm mobility
• Sleeves allow enough movement for baby to push up and reposition head if rolling over
• Deemed Hip Healthy for allowing hips and knees to flex and move while providing support
• Easy to use: place arms into sleeves, legs into sack, and zip up with baby’s arms in a flexed position
• Closed cuffs help protect from facial scratches and can be opened later for finger-sucking and self-soothing
• Sleeves left at wrist become elbow length if baby fully extends an arm
• Snug ergonomic midsection provides reassuring comfort while maintaining a secure fit
• Features a 2-way/2-pull zipper that unzips from the foot for easy diaper access
• Bridges gap between snug swaddling and loose sleeping sacks for babies who can roll but still startle
• Convertible design suits babies who prefer arms-up sleep or who self-soothe by sucking fingers
• Size selection based on body weight; do not size up: Small 6–14 lbs (0–3 months), Medium 14–21 lbs (3–6 months), Large 21–24 lbs (6–9 months)
• Made from 100% stretchy, breathable, soft premium cotton knit
• Designed in USA and imported with multiple patents covering the design and functionality

About SwaddleDesigns
SwaddleDesigns makes swaddles, sleeping sacks and baby gifts in soft, breathable fabrics with modern prints, all aimed at one goal: helping new parents and babies get more sleep, safely. It was founded by Lynette Damir, a registered nurse and mother, after she visited families with new babies and found exhausted parents who were not swaddling because their blankets were the wrong size or too thick. The brand is explicit about supporting all families and birthing people.
