It can absolutely be gross! Especially when they wipe it on the furniture, wipe their nose with their hand then touch the toys. But to me it sounds like allergies. In Iowa the last few weeks the pollen count has been over 10! Allergies show as running nose, watery/itchy/puffy eyes and cough (from drainage). A lot of my kiddos (including myself) have been suffering for the last few weeks. It is a pain to constantly disinfect!!!! The last few weeks I have felt like all I do I wash hands, wipe noses and disinfect. I personally can't wait until fall/winter!
Good luck!
