What is the reason for the baby's increasingly poor ability to lift their head when prone?

Patient's question:

No

Doctor's answer:

From your description, it seems that the child's motor function has slightly regressed, which really warrants caution regarding the possibility of brain damage.
If the child has a history of abnormal birth, such as asphyxia, umbilical cord, three-degree amniotic fluid turbidity, or preterm birth, it is even more important to be vigilant about this possibility.
If the child is laid down too much and does not get enough exercise, it can also affect the development of their motor function.
Deficiency of calcium does not cause regression in a child's motor function.
Recommendation: It is advised to consult a local pediatric rehabilitation doctor for diagnosis and evaluation to determine whether there is developmental delay in motor function. If so, early rehabilitation training and treatment should be initiated.
The human brain develops fastest in the first year after birth, with the first six months being the fastest and most plastic. It is crucial not to miss this optimal window for rehabilitation.
