Deividas Subacius caused significant bruising and swelling to the 18-month-old girl’s right eye when he struck her.
The sick thug even sent the footage of the attack to her grandparents in a text message and demanded £130, saying he would continue to hurt the child if they did not pay him.
The couple immediately alerted police, and officers arrested Subacius and seized his phone. It contained the video, messages demanding money and threats to cause the toddler even more harm.
The baby girl was examined by medics who discovered a further eight healed fractures including to her femur, wrist, collar bone and ribs, reports say.
Subacius, 29, from March in Cambridgeshire, pleaded guilty to charges of actual bodily harm, grievous bodily harm and blackmail.
