The neurological development of small babies is not perfect, and sniffling often occurs between sleeps, but if it can be relieved on its own without any treatment, it is not a problem. If the baby appears to be sniffling during sleep, accompanied by crying and shouting, it is possible that the baby has been frightened during daytime play, and can be treated for the frightened condition, such as giving chiropractic treatment to the back and spinal acupuncture points on both sides of the spine before going to sleep, which can significantly improve the frightened condition. After the baby’s fright is relieved and improved, the baby’s cramps during sleep can be improved. So it depends on whether the baby’s cramps can be relieved on their own while sleeping, or on the length of time the cramps last.
