3wks old baby stil having a yellowish and sticky discharge? In one of her eyes. Is it normal?

Gentle cleaning with a clean cloth or tissue will remove the material.Rolling the tip of a finger from the nose down over the inner corner of the eye can compress the tear sac and open the duct over time.If the lids become red and inflamed talk with your doc.
Tear drainage . Blocked. See ophthalmologist to tell you options for treatment.
