Question
A 21-month-and-19-day-old baby accidentally hit the sharp corner of a chair’s backrest while playing, resulting in redness and swelling at the fontanelle area. The parents are inquiring whether this injury will affect the baby’s intelligence and brain development.
Answer
Generally speaking, a baby of 1.5 years old has typically closed the fontanelle, so minor collisions do not have a significant impact. As long as the fontanelle has healed with a scar, such a collision is unlikely to injure the brain. However, it is still important to observe for any abnormalities in the baby and to pay attention to diet and hygiene to promote healthy growth.
