Babies who hold their heads up at birth are usually associated with high muscle tone. Babies with cerebral palsy are usually more behind in their motor development and cannot perform the movements that normal babies of the same age can perform, such as not being able to lift their heads, laugh, sit, or grasp things. So, what is the reason for babies to hold their heads up at birth? Generally speaking, because newborns have relatively large heads, but the head and spinal muscles are still not strong enough to lift their heads at birth, babies are able to lift their heads after practice, normally at about one month. If you can lift your head at birth, it is a sign of high muscle tone. These babies are also more easily irritated, startled by the sound, cry continuously, have difficulty sleeping, are more rigid, have difficulty inserting their arms into the sleeves when dressing, and have difficulty separating their legs when changing diapers. High muscle tone in babies is usually associated with intracranial injury and brain development problems, which require early detection, early intervention and early treatment. Early intervention treatment is effective, rapid improvement, can be completely cured and does not affect the baby’s movement and growth afterwards, otherwise it will lead to poor muscle growth, produce a walking deformity state, and in serious cases it is likely to lead to cerebral palsy, epilepsy, etc.
