How much amoxicillin should a baby of 22 lb take?

My 25 lb. baby is taking 6.5 ml twice a day for 10 days. Hope this helps.
If you are giving amoxicillin (penicillin) to a baby, then it must have been prescribed by a doctor including dosage information. Follow the doctor's instructions. Do not medicate a baby with prescription drugs meant for someone else or for an adult.
Giving the wrong medication will not help, may harm, and it means that another correct treatment is not being used.
