Updated at 2.36pm: A 10-week-old baby died from ''passive smoking'' after her teenage mother cradled her on her lap during a 15-hour heroin-smoking binge in a public toilet cubicle, a court heard on Tuesday morning.
Lorraly Ng Lok-wan, 21, remained stoic as she pleaded guilty in the Court of First Instance to the manslaughter of her daughter Ng Ling-li on February 1 last year.
Senior Government Counsel Dee Crebbin told Mr Justice Thomas Gall toxicology reports found the baby had six times the known possible lethal dose of morphine in her bloodstream.
Miss Crebbin said Ng told police her Godfather had given her $1,700 to take her daughter to the doctors but she had used it to buy heroin.
During the next 27-hours, Ng slept ''rough'' in the park with her baby and smoked heroin by ''chasing the dragon'' on six occasions spread over 15 hours, she said.
Miss Crebbin said Ng only fed her daughter a little water and some vitasoy milk in a local McDonalds' restraunt during the binge.
