A 2-month-old baby’s health cannot be judged by whether or not he can hold his head up; it needs to be analyzed on a case-by-case basis. It may be related to the degree of development of the back of the baby’s neck, the softness and hardness of the neck, and the weight bias, but it is basically a normal condition. No special treatment is usually needed and the child’s head lifting can be promoted through training methods. Common reasons for this are that at around 3 months of age, the physiological curvature of the spine is basically formed, so that the neck can be more flexible and the head lifting action will be more stable. If a 2-month-old baby is heavy or has insufficient strength in the back of the neck, he or she will not be able to hold his or her head up, or will only be able to hold his or her head up at 45° for a short time in the prone position. Therefore, the inability of 2-month-old infants to hold their heads up is generally a normal physiological phenomenon and usually requires no special treatment. If at 3 months of age the baby is still unable to lift his head, he should be alerted to the possibility of growth retardation, hypoxic ischemic encephalopathy and other abnormal factors. Training methods 2 months old baby can be trained to lift the head, first let the baby lying prone on the bed, the two sides of the two arms bent in front of the chest, and then through the brighter color of the toy or rattle attraction, to encourage the baby to lift the head, in order to practice lifting the posture. Note parents can usually increase the calcium content in the baby’s breast milk or formula, but also under the guidance of a professional doctor, to supplement the baby with cod liver oil, calcium supplements, etc.. In addition, visual, auditory and tactile nervous system training can be carried out to promote the all-round development of the baby.
