along with what @mommy_faith said clean it with a warm wet wash cloth...some days will be worse then others but should go away. by 6 months my daughter's was completely gone.

Breast milk and coconut oil. put a little on a cotton ball and wipe the eye.

Put a few drops of breast milk in her eye and message the skin underneath her eye a couple times a day. My son was born with one and his ped told me to do that and it went away in a week!
