Can babies' insect bites get wet?

If redness, swelling, or itching occurs, avoid contact with water. If redness and itching appear, you can use the skin of a dragon claw fruit, extract its juice, and apply it multiple times to quickly relieve itching and reduce swelling. You can also apply household toothpaste to the mosquito bite area. Additionally, you may use floral dew (a type of insect bite relief liquid) to wipe the mosquito bite area. You can apply povidone-iodine to the mosquito bite area under a doctor's guidance to quickly relieve itching and swelling.
