What should I do if my baby's face swells a lot after being bitten by a mosquito?

The baby's face swells significantly after being bitten by a mosquito. Parents can take the following measures to relieve the symptoms: 1. Cold compress: Apply a cold towel or ice pack (wrapped in a towel to avoid direct contact with the skin) gently on the bite area to help constrict blood vessels and reduce swelling and pain. 2. Clean the affected area: Wash the bite site with running water or mild soap and water to remove residue and reduce irritation to the baby's skin. 3. Apply topical medication: Under a doctor's guidance, choose appropriate topical medications suitable for infants and young children, such as calamine lotion or desonide cream. These medications have anti-inflammatory, anti-swelling, and itch-relieving properties and can effectively alleviate the baby's discomfort. 4. Oral medication: If the swelling is severe and accompanied by allergic reactions such as itching or peeling skin, antihistamine medications like loratadine granules or cetirizine hydrochloride oral solution may be given to the baby under a doctor's supervision. 5. Monitor and seek medical attention: Parents should closely monitor changes in the baby's symptoms. If the swelling persists or symptoms worsen, it is recommended to seek timely medical attention for professional diagnosis and treatment.
