You need to tell all about your daughter. Where is her mother? In UK or abroad? If mother is in UK, what is her status?
Its understandable that people may not want to disclose some things on internet forums, but to get any advice about your daughter, you will have to disclose all her circumstances fully, including her age.
To have a idea as to what is involved, you may want to read from the link. Read from page 24 and onwards.
