DS3, age 15 months, has shingles. He's completely fine, and healing well - was just a line of 6 or 7 spots at the left side of his forehead. No itching, no temperature, no drama.
He was exposed to chicken pox a year ago when he was a tiny baby and both of his brothers had it. He didn't show any symptoms of chicken pox (I had it when I was a toddler so obviously he still had immunity from me).
I've heard that shingles is very rare in children, but I've also read that babies who have chicken pox/are exposed to it or immunised against, when they are less than 1 year old are more likely to develop shingles than children who have chicken pox when they are over 1 year old. (Well obviously, because seemingly you can't have shingles without chicken pox exposure).
HOWEVER, it can't be that rare for babies under 1 year to get chicken pox if they have older siblings, chicken pox being such a common illness and older siblings not exactly a rarity either.
Has anyone else's kids had shingles when very young?
