Becky Crandley was fed up with her son Harley, 12, after repeated complaints from Sittingbourne Community College in Kent - including detentions and isolations - due to signs of a bad attitude, so she followed through on her threat to sit next to him if his bad behaviour continued.

Becky - who revealed the school backed her surprise - is quoted by the Metro as saying: ''I constantly threatened that I'd sit with him in school if needed, and he always laughed it off. Since they've been back this year I've had several phone calls already.

''So when his maths teacher emailed last week and said about an incident, I said to her I would join him. He didn't have a clue, and he was very embarrassed for sure, I was introduced as his mum.''
