The most noticeable symptoms of jaundice are yellowish skin and the whites of the eyes; urine is usually light yellow. If your baby has yellow skin, it might be necessary to see a doctor as soon as possible. If your baby has dark yellow urine, it might be the sign that he (she) doesn’t get enough nutrition, mostly fluids. It still might be breast milk jaundice if you breastfeed the baby, don’t be confused with breastfeeding jaundice. So, if you breast feed, check your diet, everything you eat goes to your baby. He (she) might not like the taste of it. If you use formula, you might try a different one. Also, try to give more fluids (water) and definitely check with your family doctor or pediatrician. It is impossible to give the right diagnosis without looking at the baby. I wish your baby good health.
