This is a standard swaddle blanket from Akachan no Shiro. Retail price: 5830 yen. From the website...:* Newborns' necks and waists are still unstable, which puts a strain on the mother when holding them. Using this swaddle blanket reduces the burden on the mother's hands, arms, and shoulders. Wrapping the baby in the swaddle also restricts the baby's arm movements, preventing the Moro reflex. As a result, babies fall asleep more easily and sleep better. [Precautions for using this product] ・Some babies may feel constricted if the body is held too tightly, so loosen it a little if necessary. ・Always use it where you can see the baby to prevent the baby from lying face down while wrapped. ・Do not use it once the baby starts to roll over. ・The effects of better sleep and easier sleep do not apply to all babies. *We will fold the product for packaging.
