Jaundice in new-born babies is most commonly caused by immature livers being unable to remove bilirubin from the blood . Baby Stella was born several weeks early in a caesarian operation and medical experts say early births can result in jaundice , which will eventually go away . But prison sources said today that while this was explained to Miss Mack , she is understood to have been concerned about the baby ’ s high temperature . She is also understood to be under pressure from her boyfriend ’ s mother , Ms Kia Walker , to make arrangements for the baby to be taken away from the prison cell and raised in a healthier environment . Trial : Mack ( left ) and her boyfriend Tommy Schaefer ( right ) , both from Chicago , are accused of murdering Mack 's socialite mother Sheila Von Weise-Mack , 62 , and hiding her body in a suitcase at an upmarket Bali hotel . It is not known whether Ms Walker has offered to take care of her grand-daughter , but Miss Mack made it clear before the baby ’ s birth that she intended to keep her daughter with her for the permitted period of two years , should she still be in prison during that period . She and Tommy Schaefer , 21 , are facing separate trials for the same crime - the murder of Ms Mack ’ s 62-year-old socialite mother , Sheila von Wiese-Mack , who was murdered in a Bali hotel room last year . The prosecution alleges that Schaefer killed Mrs Wiese-Mack by battering her about the head and face with the metal handle from a heavy fruit bowl , after which Miss Mack helped him to force the body into a suitcase which was then loaded into the boot of a waiting taxi . The couple did not board the taxi , however , instead leaving the hotel by a rear exit . They tried to leave Bali through the airport but they did not have their passports , which were being held in a safe deposit box at the hotel - and Mrs Mack was allegedly the only person who had permission to open the box . Miss Mack and Schaefer were arrested the following day at another Bali hotel . Victim : Miss Mack with her late mother Sheila Von Weise-Mack , whom she and her boyfriend Tommy Schaefer are accused of murdering .
