This absolutely is child abuse. Emotional abuse, and neglect. Setting boundaries is part of parent’s job, and it’s a job she’s refusing to do.
The child is eight. Whether the issues that have led to her behaviour are nature or nurture based, or a mixture of both, she had no control over them.
She isn’t responsible for the genes she inherited; she isn’t responsible for the home environment her parents have created.
Yes, her behaviour sounds awful, but it didn’t arise in a vacuum. The fact her mother is so ready to blame her and just feel sorry for herself, rather than being willing to look at her part in this and feel sorry for the child she is so abjectly failing, shows that the problem lies with her, and the girl’s father of course.
What seriously can an eight year old child do in this situation? Nothing. She has no adult tools, capacities or resources at her disposal whatsoever. She won’t even know why she’s behaving like this herself.
The parents have those adult resources etc, but they’re choosing to do absolutely nothing, just sit by while their daughter is clearly struggling and unhappy, and make her the bad guy. They chose to have this child but now she’s not what they expected, they cba to learn how to parent her properly. Sick.
And the number of people joining in with the “blame the child” mentality that invariably crops up on threads like this is also sickening. This is why child abuse is still such a problem in our society: because too many people genuinely think children are the problem and to blame for challenging family dynamics, not bad/ineffective/neglectful/abusive parents.
OP yes, I think you should report them if you can, hopefully they would meet the threshold for Early Help, but that is something the parents have to choose to engage with. I doubt the situation would meet the threshold for non-voluntary intervention, social services being as overstretched as they are. So it might not achieve anything, but at least you would have tried. Obviously if your friend realises it’s come from you, though, that’s your friendship gone. Could you do anything via the school?
Thank you for caring about this child anyway. Too many people really don’t care about vulnerable children in situations like this, preferring to demonise them and exonerate the parents. That’s the culture we live in.
