What can be used for insect bites on a four-month-old baby?

For a four-month-old baby bitten by mosquitoes, you can apply medications externally such as honeysuckle dew or Wujipaste. Mosquito bites typically result in symptoms like redness, swelling, and itching. At this time, essential balm should not be used. Instead, alkaline substances can be applied for relief, such as rubbing a wet bar of soap on the affected area. It is also important to maintain cleanliness of the bitten area and avoid scratching with hands to prevent infection.
