Is it normal for a newborns white of eye to be grayish yellow like. and for him to sleep so much. he is only awake for a total of 3 hours a day?

Yes and yes: The sclera, the white part of the eye, is thin in infants allowing you to see the underlying tissue which is black. This gives it a grayish blue color. Also newborns do sleep alot - be thankful, it doesn't stay that way.

Jaundice?: What you describe could indicate jaundice. While it is usually benign, severe jaundice (kernicterus) can actually cause brain damage. I would recommend having your newborn seen by a pediatrician asap.

No: All of this is abnormal and can represent multiple internal organ problems dont wait.
