Jaundice

Baby is 1 week old and breastfed. Yesterday we were sent to do bloodwork to check bilirubin levels due to some yellowing of the eyes and skin on her face. The results came back high (as expected) at 12.4 mg/dl however our provider is out until Monday and we can’t get anyone else to tell us next steps.

Anyone with experience with jaundice and have any idea if this will require phototherapy or if sunlight and increased feedings will help it on its own???
