The head circumference at one month is still in normal range so you should not worry about it.

This is within the upper normal range for infants at that age. Measurements will also vary some by who does it and can vary at the same encounter. The pediatrician can also readily discount the idea "hydrocephalus" or other expansion under pressure by simple measures on physical exam.
