These spots have appeared on my 3 yr this afternoon. Under her armpit and down her side, there's also a couple on her knee. She's totally fine in herself, no temperature and the spots aren't itchy. They don't appear to spreading elsewhere on her body yet. Could it be chicken pox? There's so many different images on google it's hard to tell and I don't think I've ever seen it in real life! Not that I can remember anyway!
