Police investigating the tragic death of a Tarro toddler in JUNE have now arrested the little girl's mother.
The 22 year old was taken into custody at her Tarro home at about 8am this morning and is expected to be charged with manslaughter.
She's currently being questioned at Maitland Police Station.
It comes after the woman's former boyfriend was charged last week with the toddler's murder.
At the time detectives said the 20 month old had suffered significant internal injuries.
She was rushed to John Hunter Hospital on June 19 suffering cardiac arrest, but sadly couldn't be revived.
Detectives are continuing their inquiries into her death.
