The methods to rule out cerebral palsy in 2-month-old babies are as follows: 1. Babies who have difficulty sucking, are too quiet or too easily provoked, do not forage around when they are hungry, do not take the initiative to come up and suck when they see their mother’s nipple or pacifier, and when they are fed, they suck without greater sensation and weakness, and are prone to choking and spitting up, need to be brought to the attention of their parents. The mouth of a baby with cerebral palsy is always open and you can see drool coming out. In addition, when the baby is 2 months old, he or she will cry a lot and is difficult to be soothed, but even if he or she is well fed and sleeps, it is difficult to be soothed. If the baby is particularly quiet and indifferent to the surrounding sounds, light and other stimuli, then we must pay enough attention to it. 2. Baby’s movement: The movement development of cerebral palsy babies is more backward than normal babies. This indicates that the baby’s movement is obviously lagging behind that of children of the same age. In addition, at 2 months of age, a baby with cerebral palsy has a different ability to gaze and follow the eyes than a normal child. Parents must pay more attention to this.
