This is a wearable swaddle that helps babies sleep soundly. It gently wraps the entire body, allowing the baby to maintain a secure posture, similar to being in the mother's womb, which helps them sleep peacefully through the night. This is a hands-in type. Size: M Pattern: Lemon Material: 95% Cotton, 5% Spandex Weight: Approximately 140g I used it about 3 times, but it quickly became too hot, and I didn't get a chance to use it much before my baby outgrew it, so I'm selling it. There are no stains or pills, and it's in very clean condition. There are some wrinkles due to home storage.
