My daughter is 15 months old. She started daycare two months ago now. She was recently treated for bilateral ear infections. She persist with a dry cough. It’s be ongoing for 6-7 weeks now. Any suggestions?

I’ve tried Vick’s vapor rub for babies

Cool mist humidifier

Saline nasal spray

Boogie sucker

I’ve tried to make honey with lemon and make my own cough syrup.

I feel bad she coughs almost all

Night!
