I think my 16 month old has chicken pox. He has been under the weather for a couple of weeks, culminating in temperature and tiredness with yucky nose over hte last couple of days. Today he came out in spots all over. At first I thought non-specific viral rash, but they have developed more and I think its chicken pox. Do I need to take him to a doctor? Ds1 has not got it (he's 4.5). In fact, he seems immune to it as he has been exposed by others many many times and not got it.
WHat do I need to do?
