Paracetamol syrup in 5 hours + wiping body with wet cloth frequently can reduce fever. Don't wipe the chest area with wet cloth. Rest of body you can wipe. Do it atleast one time in every 30 minutes.
wipe with wet cloth. note that the water used to wipe shouldn't be extremely cold to avoid convulsions. then try administering paracetamol drop 0.4 ml or as per your child's weight.
