I agree, call the pediatrician. Ours had my son on Children's Claritin for seasonal allergies, but he was older than 13 mos. In my opinion, sometimes they have to just to just get acclamated to their surroundings and they grow and build up tolerances. However, even tho your family has a history of allergies, there are just far too many scary flu stories on the news these days to not make a trip to the Doc to be sure.
