There are different kinds of impetigo, with different symptoms, but it usually shows up as a cluster of little red blisters that ooze, burst, and spread. Depending on the bacteria involved, however, the blisters may be larger and more resilient. The skin around the blisters may be red. Your baby's lymph nodes might become swollen in the area of the infection.
Most often the blistering appears around the nose and mouth, but you might also see it on your baby's arms, legs, or other areas. Multiple patches are common. As the pus dries, it forms a yellowish-brown crust or scabs that look like honey or brown sugar.
