### Patient: Doctor, my baby has been having trouble feeding, cries a lot and has an irregular belly button. What could be the problem?
### Doctor: Based on what you've described, your baby may have neonatal jaundice. This is a common condition in newborns where there is a buildup of bilirubin causing yellowing of the skin and eyes, along with feeding difficulties and irritability. It can also cause irregularity in the belly button area. I recommend bringing your baby in for an exam and blood test to confirm the diagnosis and determine the best treatment plan.
