Mrs Plony: ” I recall a chapter in A House Full of Chessed where Rebbetzin Machlis kept bringing her baby to have his bilirubin tested so he could have his circumcision on the eighth day, and miraculously his levels fell to an acceptable number just in time”
She was getting his bilurubin tested so the MOHEL would agree to do the bris. As far as every doctor in the world is concerned this obsession with jaundice is one big narishkeit, and there’s no reason not to circumcise a baby who’s bright yellow.
