Why Parents Love Swaddelini
Self-Soothing Support: Our patented Hug Technology® mimics a parent’s gentle embrace to calm startle reflexes (Moro reflex) and encourage longer, deeper sleep.
Safe Sleep Design: Created in alignment with American Academy of Pediatrics (AAP) safe sleep guidelines — snug around the chest, loose around the hips, and breathable from every angle.
Grows with Your Baby: Converts easily into awearable blanket as your baby starts rolling — simply leave their arms out for safe movement.
Made in the USA: Knit with soft, high-performance yarns for durability, stretch, and skin-safe comfort.
Easy Diaper Access: Bottom flap design makes nighttime changes simple without unwrapping your baby.
Perfect for Every Stage
The Swaddelini Sleep Sack is ideal from newborn through toddler stage. As babies transition to rolling, it adapts to their natural movement — supporting self-soothing without overheating or restriction.
