Question
Does using a comb to scratch a four-month-old baby’s fontanelle affect their intellectual development and brain growth?
Answer
At this age, a baby’s fontanelle typically closes, so using a comb to scratch it should be safe. If the fontanelle has not fully closed, it may be necessary to provide adequate vitamin AD and calcium supplements. Parents should maintain an awareness of their baby’s intellectual development and health, and refer to relevant parenting books to understand the normal process of growth and development.
