Four months after the death of her fourth baby, serial killer Kathleen Folbigg wrote she hoped her diary wouldn't "come back to bite" her like another had, an inquiry into her convictions has heard.
"That's a reflection on the fact that the previous diary had been used in the manner that it had been used," she said under cross-examination at the NSW Coroners Court on Tuesday.

Margaret Cunneen SC, acting for Folbigg's ex-husband Craig Folbigg, asked: "As evidence of the truths that are contained within it?"
"As evidence of using someone's thoughts in a manner that didn't seem appropriate, as far as I'm concerned," Folbigg replied.

The 51-year-old was jailed for at least 25 years in 2003 after she was found guilty of killing her four babies - Caleb, Patrick, Sarah and Laura - between 1989 and 1999.
Six of her diaries taken from the period in which the children died are before the inquiry, used by prosecutors in past court proceedings, while up to five others are unaccounted for.
Folbigg recalls throwing one of them out but on Monday denied it was because it contained significantly incriminating material.

"I didn't kill my children and these diaries are a record of just how depressed and how much trouble I was having and all of the issues that go with that," she said.
Continuing her evidence on Tuesday, she told Ms Cunneen that she had treated the diaries as if she was writing to a close friend and signed them off as "Kathy".
In November 1997, Folbigg wrote: "With Sarah, all I wanted was her to shut up, and one day she did".
The following month, she wrote: "Laura's a fairly good-natured baby, thank goodness. It has saved her from the fate of her siblings".
Laura died in March 1999.
Ms Cunneen cited a July 1999 entry in Folbigg's diary which reads: "I just pray it doesn't come back to bite me like my '97 one has."
Folbigg denied hiding one diary - later found by police - within a crocheted bag, wrapped in clothes and inside a blue container in her wardrobe.
Her evidence continues.
Former NSW District Court chief judge Reginald Blanch QC, who is presiding over the inquiry, will prepare a report on its results for the NSW governor.
