elevated bilirubin/jaundice

momma • Angel mama to my son 💗 earth mama to my daughter

I had my baby yesterday, she is not even 24 hours old yet. They tested her blood at six hours old and said her jaundice levels were at 3.7. They said its not high enough for a phototherapy light but they want me to supplement with formula since shes not getting the hang of breastfeeding just yet, (shes only 15 hours old!!!) I really do not want to supplement but I want to do what is best for her, i looked it up and saw 3.7 at six hours old isnt even that high or considered jaundice but they said it will most likely keep getting higher. there is another blood test in an hour to check her levels, what would you do or what have you done in similar situation?
