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."
