A chef accused of murdering his 22-month-old stepdaughter is "strongly suspected" of punching the toddler, a court heard.
Erin Tomkins died of multiple injuries at Sheffield Children's Hospital shortly after midnight on 22 May 2018.
Martin Johnson, 20, from Sheffield, denies murder and two counts of causing her grievous bodily harm with intent.
Sheffield Crown Court was told he is the "only person who could have been responsible" for the injuries.
The toddler was just a few weeks short of her second birthday when she suddenly collapsed in front of Mr Johnson - who claimed they had been playing "high fives" - at her home.
Hospital staff found bruises on her face and body, bleeding to both eyes, bruising and bleeding to the surface of her brain, which was also swollen, the court was told.
Prosecutor David Brooke QC said she had suffered "10 areas of impacts to the head and face", a broken arm and a number of fractures to her spine in the weeks leading up to her death.
He told the jury the injuries were part of a "pattern of behaviour" by Mr Johnson.
Mr Brooke said a pathologist "strongly suspected punching" caused a number of bruises around the little girl's ear.
Jurors heard Mr Johnson was staying with his partner, Erin's mother Kira Tomkins, at the time. The couple also have another daughter together.
Miss Tomkins, then 18, told police Mr Johnson would get angry because Erin would scream when he put a nappy on and get upset when he was around, the court heard.
