Hot compresses are not recommended after a child has been bitten by an insect that is red, swollen and hard. When the baby is bitten by mosquitoes, the skin will often appear red, swollen, hard and other symptoms, if you do not apply ointment and so on in time to give the baby to reduce swelling and stop itching, the baby is likely to scratch and thus lead to infection. After the baby was bitten, it is recommended not to give the baby a hot compress. However, you can give your baby a cold compress on the red and swollen part of the bite, because cold compresses play a role in constricting blood vessels, while if you use a towel to apply a hot compress, it will instead play a role in activating the blood, so that the toxins that may be produced by mosquito bites will spread, etc. You can also apply cold compresses to the red and swollen part of your baby’s bite. You can also put soap and water on the baby after being bitten by the bugs, etc., to relieve the itching symptoms of the baby.
