Our son is 4 weeks old. in his one eye allot of yellow colored mucus is forming its like tear drops but yellow in color we are cleaning it every feed. eye are not red. but the mucus the same

Common: The tear drainage in humans is through a channel beneath the inner corner of the eye. In many infants these may plug up with debris & lead to such crusting.Gently rolling your finger tip from the inner corner down can sometimes flush this debris & open the channel over time. As long as the eyelid does not become inflamed you can just wipe this away as it occurs.
