Child’s fontanelle accidentally struck, parents worry about impact on intellectual development.

For babies aged 1 to 6 months, weight (kg) = birth weight (or 3 kg) × age × 0.6 (kg); for babies aged 7 to 12 months, weight (kg) = birth weight (or 3 kg) × age × 0.5 (kg); for children aged 2 to 10 years, weight (kg) = age × 2 + 7 (or 8). Full-term infants have an average height of 50 centimeters, and they grow approximately 25 centimeters in the first year, so they are about 75 centimeters at one year old; thereafter, they grow about 5 centimeters per year on average, so the height of children aged 2 to 12 years after that (centimeters) = age × 5 + 75 (centimeters). Any height that is more than or less than 10% of the standard is considered abnormal.

A baby’s height is generally between 55 to 65 centimeters at two months, but growth rates vary among children, influenced by factors such as genetics and nutrition.

At five months and ten days old, the baby has only gained 20 grams, and has been constipated for a full month. It may be necessary to examine the baby’s diet for balance and consider supplementing with necessary nutrients.

A 13-year-old student inquires about the possibility of still growing taller, providing their parents’ heights and their desire to grow. Respondents offer nutritional advice during the growth period and potential medical intervention options.

Inquiring if a 17-year-old boy with a height of 157 cm still has the possibility of growing taller.

A 20-month-old baby is found to have severe calcium deficiency, with an open fontanelle, lack of appetite, night crying, occasional twitching, thin and yellow hair that is more relaxed, and lowest ribs standing out compared to others. Despite taking calcium and vitamin supplements as prescribed by the doctor, there seems to be no improvement. I would like to inquire whether the baby truly has a severe calcium deficiency, what effects it may have, and if it’s possible to improve the condition.
