My son who is 4 has blue veins on the side of his cheeks, across his chest and almost like a star in the middle of his rib cage. I notice they are more prominent or really more veins across his chest shows year after year. He is fair skin. The veins are visible at any moment in time, not just after bath time. He has a lot of protein, rice and fruits in his diet each day. Is this normal? He is not overweight or under weight either. Height and weight he is in the 80th percentile.
It's normal to have visible blue veins in fair skinned babies. Due to fair skin they are more visible which are not in dark complexion babies. Please don't worry on this. Hope this helps to relieve your anxiety.
