DD (16 months) has about half a dozen small spots by the back of her shoulders, chest and back. They are red with yellow or clear pus inside (YUCK) and they are raised. They have come up in the last 18 hours. She doesn't seem to have a temperture (well she does feel a little hot) and is playing quite happily. There was a case of chicken pox at her nursery. Is it the dreaded pox or something else or just bites from an insect (we have been to a butterfly farm yesterday)?
