Question
The baby often sleeps on one side after birth, causing the head shape to be uneven and angular. Does this mean a calcium deficiency?
Answer
The fontanelle on the top of an infant’s head typically closes between 12 to 18 months of age. The condition of the fontanelle closure is an important indicator of brain development. If it closes before 6 months, it may indicate microcephaly or underdeveloped brain; if it hasn’t closed by 18 months, it could suggest issues like hydrocephalus, rickets, or cretinism. A bulging fontanelle may indicate increased intracranial pressure, possibly due to meningitis, encephalitis, or vitamin A poisoning; a sunken fontanelle may be due to dehydration or malnutrition.
