hi! my baby's level was 97 when discharged and then 2 days later, it was 191. i did traditional ways to get it down, my mom went to jin tai mart and ask for herbal bath(it's like a flower) for jaundice. i bathe my newborn 2 times per day till the next check. the second check was 181 and the third check was 93(the second check i still bathe my newborn 2 times per day and once per day before the third check). so my baby was discharged from it and don't need to come back. i have attached the pic. it look something like that.
Are you breastfeeding? If yes, it could be breastmilk jaundice. Try mix feeding: breastmilk in the day and formula milk at night. My baby has high jaundice too and is already 5 weeks old. It helped to reduce the jaundice but not enough for a 5 week old baby hence we just switched to full formula milk hoping it will reduce faster. Also, the more baby poops and pees, the faster the jaundice will drop. Do not “sun tan” your baby as baby will be dehydrated.
