The clinical manifestations of babies with cerebral palsy in the third month of life vary according to the degree of cerebral palsy and their own conditions. Generally speaking, they can show postural fixation, difficulty in feeding, and backwardness in growth and development. 1. Fixed posture: Brain injury in babies with cerebral palsy can lead to abnormal muscle tone and postures such as ankylosis, which can occur one month after birth, and stiffness of limbs during bathing. 2. Difficulty in feeding: Infants with cerebral palsy may have difficulty in feeding, which may lead to stagnation of growth and development, body weakness, reduced voluntary movement and decreased muscle tone. 3. Lagging growth and development: the baby’s speech and motor development are obviously delayed, and at three months old, the baby is often unable to hold his head up or chase after objects and sounds. Parents should be alerted when their three-month-old babies show the above symptoms, and are advised to consult the pediatric department of a regular hospital as soon as possible, so as not to miss the opportunity for treatment.
