My twin boys also have this same problem. Worse is that they have it all over their body for a week. no itchy but red dots, a bit swollen (like hong mo) like rashes. Brought to paed and he said it was some kind of viral rash. In the end, i did not give him any med, just keep them clean, apply California Baby calendular cream on them. It lasted about 10 days. The rashes then went away.
