A woman accused of attempted murder following the discovery of a newborn boy in a drain in Sydney's west is likely to apply for bail next month.
The 30-year-old did not appear at a brief hearing at Penrith Local Court on Friday and her lawyer indicated she might apply for bail when the matter was next heard on December 12.
The boy was originally estimated to be two to three days old when found last Sunday, but court has heard that he was born in the early hours of November 18 before being placed into the drain.
If the allegation is true, it means he survived in the Quakers Hill drain for up to five days before being found by a passing cyclist.
Police suspect the baby was squeezed through the drain's narrow opening and dropped about 2.4 metres. Several people worked together to lift the heavy slab covering the drain to get him out.
The woman has admitted to putting the infant down the drain, knowing it may kill him, police say.
The baby is in the care of NSW Family and Community Services.
It will be up to the state agency to assess what happens to him.
The baby was taken to Westmead Children's Hospital in a serious condition after being rescued, but was discharged on Friday, a spokeswoman confirmed.
