Dosage is by weight not age.

The recommended dosage of aspirin varies a little but it is between 5 and 15mg/lb every 12 hours. Be safe and pick the middle of it and go for about 10mg/lb every 12 hours. This usually works well and seems to be pretty safe. Aspirin can cause gastrointestinal upsets and ulcers so use with caution.
