Can breast milk still be used for feeding?

Patient's question:

Main symptoms: Jaundice
Onset time: 34 days after birth
Laboratory test results: Alanine aminotransferase (ALT) 29.8, Aspartate aminotransferase (AST) 59.1, Total bilirubin 146.6, Direct bilirubin 17.1, Indirect bilirubin 129.5
Urine test results were negative (once)
Breast milk test positive 1.83 × 103
Previous treatment and effectiveness: Stopped breastfeeding for one day, jaundice reduced

Doctor's answer:

Currently, the jaundice has not completely faded, and there is a high possibility of breast milk jaundice. Generally, it is recommended to stop breastfeeding for three days and wait until the jaundice has mostly faded before resuming breastfeeding.
Besides, I don’t know if your child’s cytomegalovirus (CMV) is negative. If the child’s CMV IgM is positive or the CMV DNA is positive, the child will need treatment for CMV. If the mother’s CMV IgM is positive, it is best not to change the diaper, as this can help prevent the spread of the virus.
