Jessica Kitching, 25, was collecting her daughter from school when she launched the savage attack on Charlene Harkin - known as Charlie.
The mum told the court she considered changing her child's school as a result and was also left terrified that Kitching would come to her home.
Kitching pulled the 37-year-old to the ground by her ponytail and knelt on her chest in front of horrified school kids.
As well as a suspended sentence, she was ordered to complete 15 days of rehabilitation activities and complete 60 hours of unpaid work.
Kitching pleaded guilty to assault occasioning ABH but was spared jail as her daughter would suffer.
