Why do 7-month-old babies clench their hands and feet?

Patient's question:

No

Doctor's answer:

Considering it may be caused by calcium deficiency, calcium deficiency can easily lead to baby's (scalp hair loss), crying, and poor sleep. You can check for trace elements to see, and supplement with vitamin D by taking fish oil orally. Add appropriate calcium supplements, pay attention to getting more sun exposure to promote calcium absorption, and it will gradually improve. Wish your baby healthy growth.
