What quantity of Advil should I give him? He weighs 29.2 lbs and is 18 months old. We do not usually give him Advil, we use Tylenol.

Based on the child's weight of 29.2 lbs, you can give them between 65 and 130 mg of Advil. The recommended dose is 3 mL, which is equal to 120 mg. It can be repeated every 6 to 8 hours, up to a maximum of 3 times a day. Remember to keep the child comfortable and well-hydrated, and if they are still unwell after a few days or if you have any concerns, don't hesitate to consult a healthcare provider.
