Sorry to hear about your child, my son too had chronic sinus problems, he is now 11 years old and still suffers. After going to an allergist, we found out that he is allergic to dust, which means i clean a whole heck of alot, but it still doesn't really help, i've been praying that he too "outgrows" it. He breathes through his mouth and has an especially hard time eating. He has bad breath and at first i thought it was a dental thing, but the dentist said it was from post nasan drip...he cough and hacks alot especially first thing in the morning. Good luck, be releived to know that he is not the only one suffering...
