keep the baby cool at all time (heat/high temp will only worsen the condition)..ensure the baby is fed well, ideally breastfeeding. however, if doing bf, the mother must avoid eating anything spicy, no chillis, no blackpepper, no herbal remedies, no makjun or whateva (all the typical "heaty" things)..these stuff willl again makes things worse

dude..monitor the mother's food intake too...refrain from all those food or medications that could worsen the jaundice
