DD is 3 and woke with a rash on her face on Friday morning. It seemed to develop into small blisters so I thought chickenpox and kept her off pre school. 2 days on, I'm still not sure if it is chickenpox. It's only on her face although there have been a couple of possible spots elsewhere. Shouldn't it have spread? Is there anything else it could be? She was a bit under the weather beforehand but fine now. No fever. Very little itching. Pic attached!
