Hi.
My children react to the allergens negatively whenever we visit North Carolina also. I feel your frustration! We don't believe in pushing meds, but use it as a last option. So, when our daughter's allergies got worse than ever we gave her echinacea and golden seal root (capsules go down well). It's customary to wash both of their sheets and pillow cases every 3 days during pollen season -- especially when there's been no rain for a week or so. Pollen gets on clothes, inside the car and we bring in it on our shoes, hair etc., so we religiously dust and shampoo the carpets every 2 months during the warm season. The Eureka carpet shampooer saves us bundles. Dusting, and keeping the air on instead of opening the windows during high pollen count days works wonders! The babies must have water, when the dryness and coughing gets going, they'll need that water as will you. On the highest peak days, we give them liquid benedryl and it calms things for more than a week. It's our policy to resist Claritin, and those harsh medicines which all cause nose-bleeds, coughing, headaches, sinus infections and worse symptoms. You can look up all of their side effects online to make your best decision. I hope you'll try to the at-home changes and modest cure like Benedryl first, before subjecting your little one to the other stuff. All the best to you and yours!
