Question
A four-month-old baby exhibits abnormal muscle tone behaviors including tilting the head back, swaying the body during breastfeeding, fingers clenching or spreading out, not bending hands while dressing, and crossing legs when held. Parents are worried whether it is due to hypermuscular tone.
Answer
Based on these symptoms, the possible cause is a lack of calcium. It is recommended to undergo a detailed examination to determine the specific situation and supplement vitamin D or calcium as necessary. As newborns adapt to the external environment, with increased holding, the baby’s skeletal support and muscle tone gradually strengthen. It is suggested to engage in tolerance training and to cherish the time spent accompanying the child’s growth.
