The first thing to look out for in a one-year-old baby with yellow palms is whether they have recently been fed too much food such as carrots or sweet potatoes; the symptoms of yellow hands will generally diminish after such babies have reduced the feeding of carotenoid-rich foods. In addition, if your baby has a disease of the liver and biliary system, such as hepatitis, he may also develop yellow hands, a sign of jaundice, which should be actively treated at this time.
