At 13 months, a head circumference of 48 cm is within the upper normal range, especially if the baby’s development, activity, and milestones are normal. Weight 9.7 kg and height 77.5 cm are also acceptable for age. Some children naturally have a slightly larger head due to family traits.
Next Steps
• whether head size is increasing too rapidly,
• developmental delay,
• vomiting, seizures, irritability, abnormal eye movements, or poor feeding.
If none of these are present and milestones are normal, usually there is no immediate concern. Kindly continue regular growth monitoring with your pediatrician.
