Thanks for the query
Tab Indiclav 375 consist of 250 mg Amoxicillin
and 125 mg Clavulinic acid, you can use Augmentin duo
syrup contains 200 mg Amoxicillin and 28.5 mg clavulinic acid. Drug dose depends on amoxicillin base 20-40 mg/kg/day in three divided doses. I think your child must be around 15 kgs, so you can give duo syrup 5 ml thrice a day.
I hope this answers your query effectively
