yesterday had a chat with my boy's cc's director. She was sharing her experience of her boy battling with a bout of nose prob, and was put on 7 whole months of anti-histamine, finally she consulted a specialist and realised her boy is actually allergic to dust mites. So she got rid of all stuffed toys, rugs, carpets, fabric sofa. And bought anti dustmite pillows, sheets etc even a washing machine that can support hot water washing and his condition improved!
