A. kindly before giving any kind of medication always consult your treating doctor onccae for knowing about the proper indication,dosage and duration upto which dose needs to given this is commonly considered as normal as per the age ,for this ,you should not worry it is acceptable for now and this may not require any medicine or treatment .
