The blisters around the moth and eyes might indicate an insect bite. A mosquito bite can bit several times in different areas of the exposed skin resulting in red bumps that are unevenly placed. If the bumps have occurred overnight or a very short period of time, it definitely indicates an insect bite.
The other possibility is an allergic reaction
but usually the hands, forearms or trunk may also be involved in such cases.
The presence of fever
indicates ongoing infection, most likely upper respiratory tract
infection as you you said she stuffy.
Kindly give paracetamol
to bring down fever and show her to your Pediatrician
if the lesions progess.
