Sibling rights

I feel that people should have sibling rights. I have been going through a kinship assessment for the last few months so i can bring up my little brother who is 1, to be unsuccessful for absolute ridiculous reasons. I applied to become his kinship carer after our mum died in june last year. I haven't seen my brother in over 10 months now, all i have had is 3 photos. Social work has said I won't be getting contact with him any time soon as he is being adopted and he might or might not be told about me and my family in the future, this seems to be happening far too much, children being kept away from their birth families and its wrong. I should be allowed to form a relationship with my brother so he can grow up knowing exactly where he came from and that we love him.
