Question
An infant aged three to four months, with a height of 74 centimeters and a weight of 10 kilograms at three months, has not shown any growth since then. Despite paying attention to introducing new complementary foods and having a good appetite without being picky, the child had trace element tests at four months and ten months, which showed high phosphorus levels and iron deficiency. Both tests indicated mild rickets. The parents are worried and want to know how to ensure the child continues to grow healthily.
Answer
Do not worry too much; not every month will see significant growth.
