Yeah, don't mess with it, it will work itself out on it's own. If you need to help a blocked tear duct, or your baby's eyes are "congested" here is a little tip: you can wipe away the excess ooze with a washcloth dampened with water, and wipe from the inside of the eye (part closest to the nose) outward in a sweeping motion. Don't apply pressure and be very gentle.....then....
If you are breastfeeding, you can squirt your milk into the baby's eye or onto the eyelid. Breast milk has anti-bacterial properties and will help clear the congestion and prevent infection...and may even help flush out a stray hair.
Good luck.
