My 10 month old dd has been sneezing anywhere from clear to yellow snot for the past 2+ weeks. She'll sneeze, and I'll look over and the snot is hanging down to her chin. She did have a cough for about 5 days, that seems to be getting better now. Other than that, no other symptoms. It was brought to my attention by a family member that she may possibly have a sinus infection, since the runny nose/sneezing snot issue is not improving. I have been using saline drops in her nose and then suctioning with a NoseFrida and/or bulb syringe. Is there anything I can do to help rid this problem for good. Any safe & effective natural remedies for sinus infections in babies??
