I think, according to TH parents, they didn’t have issues with bios mums parenting if I remember correctly? I’m sure that was mentioned early on in the trail but
@Tortoise would be best placed to clarify that.
I think this poor boy lost his mother, was unaware of the reasons why, had his entire world turned upside down, moved from one home to another home and then another, then found out (rather harshly) his mother was in prison, got stuck living in a house with a woman that despised him and was jealous that her lovers attention was taken away from her. Then was subsequently tortured in every sense of the word. I can very easily see how this poor boy ended up self harming and “acting” out. He was 6! Jesus Christ, I don’t think even as an adult you would come out of that situation unscathed and without needing support. I don’t think he was a problem child, I think he was a child desperately reaching out for some stability and love and was penalised massively for it
