Infant sleep jumping is because the child’s nervous system is not well developed, the excitation and inhibition process is not yet perfect, after being stimulated easily caused by excitement. This should be a normal phenomenon and does not require special treatment. When the child startles, the mother can use her hand to press any part of the child’s body and gently soothe it, which can calm it down. If a newborn baby has a startled jump, the mother can calm the baby down by gently soothing the baby’s body or hands with her hands to make the baby feel a sense of security. The mother can rest assured that the newborn’s startle has no effect on the development of the brain. As the baby’s age increases and the nervous system slowly develops, the startle will slowly disappear and no special treatment is needed. If the child is accompanied by other symptoms, such as periorbital cyanosis, impaired consciousness or birth asphyxia or lack of oxygen, you need to go to the hospital for an examination and need to rule out convulsions.
