Police are warning parents to behave if they go to schools - or face a fine.
On Facebook, the Northern Neighbourhood Policing Team says it's had a number of reports about parents behaving badly.
Officers say if you have an issue involving your child you can follow appropriate channels to discuss it.
But they say the Education Act 2001 bans violent, quarrelsome, indecent or disorderly behaviour on school premises - as well as profane, obscene, indecent or threatening language.
If you break the law, they say you could end up facing a fine of up to £1,000.
