Jaundice will reach its peak on the 8th day from birth. It can take up to 1 month for it to go away and the only way is for baby to have regular bowel movements and pass motion. Sunning actually does not really help, only help in baby's coloring. You should cut down on ginger intake until baby jaundice goes away.
Just monitor whether baby's yellowish tinge starts to go away. If you want, can actually go back to pediatrician to do another
blood test to check jaundice level.
