how old is the newborn ? can he open the eyes fully at any given time ? does the baby appear to see?
a small amount of lid droop is considered normal, however over the first 6-12 weeks of life, it should improve. It seems today it has worsened, or perhaps a better way to state it is that it has behaved differently, it needs to be evaluated by an ophthalmologist. There are certain neurologic issues that may need to be considered. Most often though, a slightly droopy lid is just that and nothing more and requires no attention unless it is something that affects the eye's ability to see. I wish him well, Dr. Stevens
