A mother has today admitted a charge of cruelty against her son allegedly murdered by her boyfriend.
During her trial Chloe Thomas, 25, had denied being cruel to 17-month-old son Finley Thomas.
But she today changed her please to "guilty" when she was asked about the allegation if she had "wilfully assaulted, ill treated or neglected" the toddler between April 2013 and September 2014.
It comes after police statements given by Thomas were given to Cardiff Crown Court in the trial of Sean Buckley for murder.
Thomas, who is accused of allowing her boyfriend to brutally abuse toddler Finley Thomas, said her son had begun calling Buckley "Daddy."
Cardiff Crown Court heard a transcript of Thomas' police interviews, in which she denied Buckley had ever abused either herself or her son.
The court heard text messages were sent from Thomas' phone to Buckley after Finley died in hospital, which showed Thomas going over what happened with her son as well as referring to explanations about older bruising doctors found on his forehead and on his ear.
The prosecution allege Buckley repeatedly abused Finley in the months leading up to his death with Thomas covering up for him, before he used a white garden chair to kill the toddler in a "deliberate and brutal" attack.
Finley suffered "catastrophic" head injuries after allegedly being attacked by Buckley at his home.
After his death doctors found evidence of previous multiple bleeds and injuries to his head and spine which were consistent with "non accidental injury."
Buckley denies murder.
He and girlfriend Thomas, both of Tonypandy, Rhondda, had both denied cruelty to a young person under 16 until her change of plea.
The trial continues.
