Ds 2.7 has a few spots developing on his face, they have blisters. He says they're not itchy and doesn't have a high temp. He seems well in himself apart from being rather testy today. Not sure what else it could be. There are no other spots on his body but he has spotty eczema so difficult to see. He had 2 spots yesterday and now has about 12! Not all have heads on. Thanks for any advice.
