First, it is '
jaundice', if you want to research it further.
Second, if your wife likes this doctor, you can probably stick with her. She can talk with the nurses at the hospital if she wants further lactation advice. My son didn't get it at first, he had a lot of trouble figuring out the latch. We didn't go to bottle early on, and he almost lost 10% of his birthweight, which is the "there's something wrong" level. After about two weeks (iirc), he figured it out, and we used both breast, pumped breastmilk in a bottle, and formula interchangably for the next 9 months.
Possible complicating factors for us included her large breasts (something about the curvature affecting the ability to latch), and the high doses of pain medications she was on following the C-section.
So, encourage her to stick with it, while you keep your kid nourished. Just because it didn't happen the first two days doesn't mean that it won't.
