Girls, mosquitos bit my son. I took Raptor, but it doesn't seem to help at all. It looks like there is an allergy from the bites, I'm applying Fenistil, but new bites appear. In pharmacies and markets they sell lotions for children from 2 years old. By the way, I am in Istanbul. I don't know what to do ??‍♀️. Please help!
