Hint : 📅Think about which fontanel closes later in infancy.

Correct Answers:

  • The anterior fontanel is open.


Rationale :

👶The anterior fontanel normally remains open until about 12–18 months of age, making it expected in an 8-month-old infant.

🧠The posterior fontanel typically closes by 2–3 months, so it should not be open at this age.

⚖️Fontanels are not expected to be equal in size, as the anterior is normally larger than the posterior.

⚠️Molding is associated with birth process changes and should not be present at 8 months.

📌Core message

The anterior fontanel remains open in infancy, while the posterior closes early.
