Amina Agboolha was kicked six feet across a room by 19-year-old Dean Harris. He called 999 shortly after the incident.
When paramedics arrived at the scene, the toddler was found to be unresponsive, looking like a “rag doll.”
Harris said that he “didn’t mean to cause her any harm.”
He expressed remorse for his actions, but the court found him guilty of murder.
Det Ch Insp Jon Hutchinson, of Cambridgeshire Police, said: “His evil actions have resulted in the death of a young girl who had her whole life ahead of her.
“Harris used completely disproportionate violence against such a tiny child.
“There is never an excuse to hit a child and he should have had no doubt what the potential consequences were of using such force on a two-year-old.”
Cambridgeshire County Council, whose social services had warned about Harris, said “a serious case review into this tragic case is currently being undertaken by the Local Safeguarding Children’s Board to see if there are any lessons to be learned for agencies from the tragic death of Amina”.
Amina’s liver was found to be split by Harris’ kick. She also suffered from a broken arm, bruising and bite marks on her face and arm.
