Emma Wilson, 25, was sentenced to life in jail with a minimum of 14 years for the murder of her 11-month-old son Callum.
Speaking following the sentencing, Det Supt Ian Hunter said:
The sentence today is a reflection of the abuse Callum suffered at the hands of someone entrusted to care for him and the pain he must have felt during his short life.
It also reflects on the dedication and efforts of the investigating officers and prosecution team to deliver justice for Callum during what was a difficult and emotional case for many of them.
Of course, sadly it does not bring Callum back and our thoughts will always remain with him.
Adrian Foster, from the Crown Prosecution Service (CPS), said: "This was an extremely difficult and complex case to prosecute.
"Without any eye witnesses, we needed lengthy and highly technical evidence from top medical experts to help provide an explanation as to why this baby died.
"The truth is that the fatal injuries Wilson caused were the culmination of a series of violent acts by her towards her son.
“We hope that the conviction and sentence will in some way help his extended family come to terms with this tragic event.
"No matter how long the prison sentence is, we acknowledge that nothing can make up for the loss of Callum. Our thoughts are very much with his extended family at this time."
Judge Justice Kramer told Wilson:
– Judge Justice Kramer
You are adept at lying and displayed a total lack of emotion throughout the trial.
You must have been the person who caused his injuries.
