I *think* you can email social services and ask whether you can please be put in contact with the family. Explain why, explain you'd like to be able to have a relationship with the child, or just know he's okay, or whatever it is you want.
@Ellie Aw so sorry this happened!! Hope you get in contact soon 🙁
@Ella oh really? Thank you x
@Ellie contact the local social services that was involved they can help x
Following, I have a little brother in care too! He was adopted about 10 years ago now, same situation as you, dad on drugs and I have no contact with him( we don’t share the same mum). X
