Tmi tmi dry booger**

My 3year old has been having this for a couple days now ( 4 5 days) and no other symptom! ... he isnt sick. No bleeding at all either.

His nose is always plugged with dry booger and I do use the saline spray.. but why is he having dry bugger like this?? He has an appointment on tuesday for something else I'll ask than. Whyy? I'm confused my first child.
