Blocked Tear Duct Vs Infection - help!

Tina

My little one always has watery eyes but the last few days have been more watery and some cream-coloured discharge and eye crusties. He’s not fevered, no swelling in the corner of his eye and his eye doesn’t seem to be red. Does that sound like just a blocked tear duct? I don’t want to ignore it if it’s an infection so curious if anyone else has had this experience. Thanks mamas!
