Sarah Morris, from Flintshire, Wales, who left the children in waist-hight water, told a court: “I didn’t think anything bad would happen”
A baby died in the bath in front of her twin sibling after their mum left the room because she “didn’t think anything bad would happen”, a court heard.
Infant Rosie Morris died while sharing a bath with her twin, the jurors were told.
Mum Sarah Morris – who denies manslaughter – told the cout the 13-month-old children were in the bath for about an hour while she was on the phone for 47 minutes.
She insisted she had been in an out of the bathroom supervising the children and had been playing with Rosie.
Morris, of Bagillt in Flintshire, Wales, said the water was about waist high on the babies and there had never been a problem with them being in the bath before, Mold Crown Court heard.
But Morris claimed she came into the bathroom to find the plug had been pulled out by the twin, who cannot be named for legal reasons, and Rosie was lying on her back with no water in the bath, North Wales Live reports.
Breaking down in tears, she told the court how she had tried to revive Rosie before running into the street crying for help, when neighbours and then paramedics came to her aid.
“I was in a bad state, a really bad state,” she said.
Morris denies the gross negligence manslaughter of Rosie in 2015 and an alternative child cruelty charge.
But in cross-examination, Oliver Saxby QC said Morris had been told on two occasions in the previous four months of the dangers of leaving babies unattended in the bath.
“Leaving these two unattended in the bath for any length of time was extremely dangerous wasn’t it?” he asked her.
Mr Saxby said she had been popping in and out of different rooms in the house, had lost track of time and was “not thinking of them enough”.
Morris said: “Of course I did, these were my children and I loved them.”
She added: “I didn’t think anything bad would happen.”
The court has heard Rosie had been in cardiac arrest when she arrived at hospital.
Giving evidence, pathologist Dr Brian Rodgers has said in the absence of some of the hallmarks of drowning, he gave the cause as being consistent with drowning, taking into account the circumstances in which she was found.
The jury heard the defendant explain her difficulties with reading and taking in information due to suffering from Mass Irlen syndrome, which stops the brain processing visual information correctly.
Morris, who also has dyslexia, said she needed written data to be printed on a yellow background and used special settings on her phone so she could read messages and other information.
She repeatedly told defence barrister Patrick Harrington QC that she couldn’t remember important conversations in the ambulance on her way to hospital with Rosie and with a paediatrician once she got there.
The judge later told the jury they “must be sure it was gross negligence” to find her guilty of manslaughter.
In his summing up after the close of the defence case, Judge Simon Picken told the jury “mere negligence was not enough” to convict her of the more serious charge of gross negligence manslaughter.
He said: “There must be gross negligence. Even very serious errors of judgement are not enough. You must be sure there’s negligence so bad you regard it as criminal.”
He told the jury they could find her guilty of that charge or child cruelty but not both. They were still entitled to find the defendant not guilty of both charges.
Both prosecution and defence counsels will sum up their cases on Tuesday morning before the final summing up of the evidence by Judge Picken.
The trial continues.
