In the majority of cases, the baby’s head can stand up at 2-3 months of age, when the child is already holding his or her head more steadily and thus is able to form a physiological bend in the neck. Children at this time indicates that the degree of development has reached a certain stage, parents in the child’s bed, will raise the head and raise the head more stable on their own. When holding the child, often still need to use the hand to hold the neck, although the child’s head can already stand up, the neck muscles are not particularly developed, and only when the child is six months old can be completely vertical hold. Therefore, the baby’s head can stand up at 2-3 months after birth, and if it still cannot stand up at 3 months of age, it should be considered to have developmental delay.
