I recently bought a used car that had been sittng for a year. Ive since found out its mold everywhere. Before riding in that car my 12 month old and I had been exposed to mold in the previous car we owned for about 4 months without knowing. I attribute his sudden illness to the new exposure because half a day after riding in the new car he was sneezing frantically rubbing his eyes. That nght he had drainage so thick in th back of his throat I had to sleep sitting upwith him. Next morning lots of sneezing by noon he was pouring snot like a faucet. That night same thing. so I got him up took him yo the e.r. . Doc sayss both ears are red he has a fever and put him on an antibiotic (he just came off one for the same thing one weekprior). Next morning he started uncontrollable coughing. He takes Bromfed, singulair, breathing treatments,
Thanks for asking gone through your question. And understand your concern Your some has allergic tendency.  If I was your treating pediatrician I would add some more thing to above-mentioned management 1. As the allergic symptoms are very much bothersome, I would advise Montelukast (singular) for at least this season.2. Assure you that it is normal to have frequent respiratory tract infection, they respond to treatment. As child grow the frequency decrease. 3 Do dusting frequently with vacuum cleaner, 4. It possibly floor carpet and room curtains is to be avoided, hope I answer your question have healthy family
