Blocked tear duct or eye infection??

Meghan

My 1 year old woke up from his nap with a huge glob of green discharge in the inside corner of one of his eyes. It’s also very watery. It isn’t swollen and doesn’t seem to bother him. I’d hate to take him to the doctor for nothing, but I’d also hate to wait if he needs eye drops or something. My DH says to wait on the doctor since he doesn’t seem bothered by it. Any thoughts??
