■[Newborn Swaddle Wrap] designed to reduce strain on the hips. This item was devised by Tamami Sato, Professor at the Department of Nursing, Faculty of Medicine, Saga University. (Registered Design No. 1594372) Newborns have unstable necks and waists, and holding them can be a burden for mothers. This swaddle wrap reduces the strain on the mother's hands, arms, and shoulders. Furthermore, by wrapping the baby in the swaddle, arm movements are restricted, preventing the Moro reflex. As a result, babies fall asleep more easily and sleep better. Thank you for looking. Please understand that this is a used item before proceeding with the transaction.
