Hi. I have a 5yr old who came to live with me aged 5mths after a brief time in foster care. I have court orders for parental responsibility and for child to live with me.
I supervise contact with both birth parents. Both have issues, mental health, substance abuse etc.
I have set rules and if those rules are not adhered to then I suspend contact. If when child was a baby and wasnt settling I would have short sessions. Mother has minimum once a month for 2hours supervised by me contact. Father has when I agree.
You are within your rights to restrict times and amount of contact if it is in the best interests of the child. The other parent would need to make a court application of a c100 (child arrangements) form which involves mediation first.
Good luck.
