What does a 5-month-old baby look like after being bitten by a mosquito?

A 5-month-old baby usually develops localized redness and swelling on the skin after being bitten by a mosquito. The bite area may quickly turn red and become noticeably swollen, forming a small red bump. This occurs because mosquitoes release a substance called formic acid when they bite, triggering an allergic reaction in the skin. The baby may become fussy or cry due to discomfort. In addition to redness and swelling, there may be mild itching at the bite site, causing the baby to try touching or scratching it with their hands. To prevent scratching, parents should promptly apply an appropriate insect repellent or anti-itch cream suitable for infants and keep the bite area clean. If the redness and swelling persist or if the baby shows other signs of discomfort, medical attention should be sought promptly.
