hey my 6 month 27 days old baby having the HC of 41 but as per WHO standards HC should be 41.7 to 45 . Is it matter of concern? please guide

A. Hello good evening !! As the baby's present head circumference is 41 nearer to average range nothing to worry ,it depends on genetics also smaller heads have less head circumference. However check whether the baby reaches all physical and mental milestones,gross and fine motor skills according to the age around 6-1.5 years age. If any delay in milestones and head circumference is not growing according to the age then consult the Doctor .
