The vast majority of newborns should not have their hands wrapped, because the wrapping of the newborn’s hands can cause obstacles to the newborn’s movement, which is detrimental to the development of the newborn’s hands. This is especially true for newborns who are relatively young and have poor hand coordination, which cannot be practiced when the newborn’s hands are wrapped, and thus is detrimental to the newborn’s motor development. The newborn’s hand being wrapped is very unfavorable to the newborn’s mobility, which can lead to irritability and crying symptoms. The newborn’s hands are wrapped up is mostly caused by parents’ misunderstanding, for example, some parents think that the newborn’s hands will involuntarily scratch the face, which will cause head and face injuries, especially for fear of scratching the eyes, but the probability of this situation is very small, just need to cut the newborn’s hand nails flat, so the newborn’s hands should not be wrapped up.
