I did a google search and could not find any connection between 23 Beta Pregnenolone and neonatal jaundice. If the MD is in USA, you could fax the AAP guidelines for initiation of phototherapy. You could copy some info from Ruth Lawrence. But I doubt it would do any good. Jack Newman's book is good for the parents to read. If the parents read his chapter on jaundice, they could then question the MD directly. It is thin ice you will be treading to get between the parents and the MD. It is best for the parents to ask questions and explore their options. If the MD does not explain his/her rationale to the parents' satisfaction they can use another MD.
