My 20 months baby... Itches anal region sometimes... Bur i didn't find any redness or abnormal things... What could be the reasons ?

A. it can be worms. deworming process is not mandatory still can be done every 6 months in babies above one year of age. Can give syrup bandy Plus 15ml at night after a full fatty meal and check for worms in the stool next day. Can also get a stool test done for confirmation. Maintain hand hygiene and before feeding hand wash .
