D.S.
J.,
Two of my 16 month old triplets are also having this reaction on their face when we are outside. I asked the Doctor and was told it is fifth disease. I was told by the Doctor that they do not treat it and that it goes away on its own over time. I was a little freaked out when she said "disease". But, she reassured me it is nothing to be concerned about. The only thing is they shouldn't be arround pregnant women while they still have it.
Hope that helps,
D.
