And just q uickly, they start as blisters (DD's started sooo quickly and spread sooo quickly I just thought it was exzma to start) they go crusty after a while, and DD needed antibiotics but after being on them for 24 hours they are no longer contagious. They were awful to look at and so itchy, and I just didn't know what was going on. They were on the back of her leg. They're common on limbs and face, but basically anywhere there's a sore, exzma etc to start which the kids scratch. Hope this is what it is, only because it's easy to treat and get rid of. xoxo
