What is it?

Blocked tear duct or pink eye? The whites of her eye isn’t red! She’ll be 3 weeks old tomorrow. She hasn’t been around anyone with a cold and she is able to open that eye. I feel so bad for her. Any of you mothers experience anything like this? Thanks for any input and suggestions. (Yes I’ll call her Doctor if it gets worse)

*Thank you so much ladies! I’ll definitely try and have done everything suggested!*
