Convinced she was in love with her 10-year-old student, primary school teacher and mother of eight Diane Brimble had his name and the infinity symbol tattooed on her chest, a court has heard.

The boy's mother told the County Court on Monday that Brimble had "hurt him in his heart" after Brimble had groomed him.

The mother said while her daughters would draw rainbows and unicorns, he drew black pictures of knives and death. She felt sickened as a mother that Brimble's offending was "under the guise of motherly love".

"The commemorative tattoo etched into her body of my child's name in the symbol of infinity coupled with her belief in spells and spirits makes me convinced that she truly believes she is meant to be united in dreams for eternity," the boy's mother said in a victim impact statement read to the court.
