Patient's question:
The child has been crying non-stop recently and isn't eating much. What age can a baby see things?Doctor's answer:
When a baby is born, they already have a reaction to light. Their field of vision is only about 45 degrees, and their vision is only 1/30th of an adult's. They can only track objects horizontally and those within 18 to 38 centimeters in front of them. Infants and young children are prone to calcium deficiency due to rapid physical development. Generally, you can give them some cod liver oil or Betalact, and also take oral calcium gluconate. Exposing them to sunlight appropriately can help promote calcium absorption. Additionally, you can feed them some scrambled egg yolk puree to increase calcium in their diet. Calcium supplementation is a long-term process.
