I've had it for years. Then I was diagnosed with Type 2 Diabetes. I tried changing my diet to suit the diabetes - low carbs, whole wheats, leafy greens - and my IBS flared up so badly. It was bad before I started taking my metformin/glucofage but it got increasingly worse when I changed my diet for the diabetes.
Newborns are also coated with a thick, pasty, white material called vernix caseosa (made up of the fetus' shed skin cells and skin gland secretions), most of which will be washed off during the baby's first bath.
No baby of any race stays the same color that they were as a newborn. He'll get a little darker. But you'll just have to wait and see. My daughter is half hispanic, 1/4 white, 1/4 black and she had a yellow skin tone till she was 10 mts and now she looks black.
