Hello,
It's good to monitor your baby's head circumference (HC) as it can provide insights into their growth and brain development. A change from 32 cm at birth to 41 cm by now is generally within normal limits, reflecting healthy growth. Measurements should be taken by a healthcare professional to ensure accuracy. If your baby is feeding well, active, and reaching developmental milestones, there's likely no cause for concern.
Next Steps
However, always feel free to discuss any worries with your pediatrician. You may take a tele consultation with me as well.
