Just to be clear to anyone new to my situation. I was the person who reported the children's situation to children's services, almost a month ago. Two years ago, I was on the verge of doing so, but my daughter stepped up to the plate and things improved dramatically. The children all confirmed that they had no worries, and lived their Daddy. Phew.
Two years on, one of the children told me that recently, her Daddy's behaviour had become abusive again, in secret. I told my youngest D, who failed to protect them. Leaving me no choice but to report to children's services.
I was then cut off. But thankfully the children did disclose to school staff and a social worker, who remains involved.
