the normal head circumference of a infant at birth is around 34 cms and at the end of 2 years is usually around 50 cms. the rate of growth of the head is usually higher in the initial few months after birth and later it slows down. as described in your history the findings are well within the normal growth curve and there is no need to be worried. if you have any concerns about development of your daughter you may consult a pediatrician for proper physical examination of your daughter and seek proper medical advice. i hope this helps.
