Thank you for your query,
These skin lesions are looking like pyoderma
as they are like red pimple, spreading and have scabs.
Antibacterial ointment like mupirocin
to be applied over the skin lesions.
But the exact diagnosis is made by physical examination, so please send the photographs of the lesions or consult your Pediatrician
for examination and appropriate treatment as some times oral systemic antibiotic may be required.
Hope I have answered your query.
