How do I deal with my babies milk spots (milium) on his face?

Spots will resolve. Milia are very common, and though frustrating for parents to see are not associated with any underlying problem. The little white bumps on the face will resolve with time and I generally recommend parents do nothing to make them go away any faster. They will not cause any permanent scarring and are not painful to the baby. Feel reassured your baby is ok and watchful waiting is the best medicine!
Milia. They will disappear on their own, in a month or so.
