What should I do for a mosquito bite? What is the dosage of Benadryl for a child?

For a mosquito bite, it is best to avoid using Benadryl and instead opt for a 1% hydrocortisone cream to be applied twice a day. You can also apply a fragrance-free moisturizing cream like Aveeno and use cool compresses to reduce swelling and discomfort. Benadryl should be reserved for more widespread reactions and should be administered according to the recommended dosage based on the child's weight. If in doubt, consult a pharmacist or healthcare professional for guidance.
