Two weeks ago, DD2 was bitten by a mosquito on her face- three bites in a row, on the same cheek. She would not leave them alone and kept picking at her face, so I covered them with a band-aid (curad brand). A day later, I went to change it to find that it had left a huge rectangular rash. So I washed her face, discontinued the band-aids, and have been applying cortizone cream to her cheek.
It's not helping. The rash looks awful, inflammed, and bright red. Is there anything else I can be doing for her? How long do these things usually take to heal?
