The jury reached their guilty verdict on Thursday.
Tahjir Smith, 4, died inside his Willow Grove home last year.
The boy's mother, Lisa Smith, and her boyfriend, Keiff King, were charged with first-degree murder and related charges.
According to Smith's confession, she and King were disciplining the boy for spilling his cereal and made him get into a push-up position. She said they then "laid the boy on the bed with his pants and underwear removed, grabbed a blue Levi's sandal and repeatedly struck him."
She said King "punched Tahjir in the back of the head," before putting him in a scalding shower and burning him.
According to court documents, Tahjir became unresponsive in the home and went in and out of consciousness. Police said that's when his mother called police and then began to walk down the street with the child.
Paramedics arrived to find the boy limp and unresponsive. The boy was taken to Abington Memorial Hospital where he was pronounced dead.
