I can't call him my son because I am his foster carer (although we have permanence so we have been together a while and will be together for many more years yet, he's definitely part of our family). He has profound and multiple disabilities, he faces huge challenges every day, he's unable to walk, talk or even hold his head up without support but the clever little boy can now reliably identify objects up to three (he uses a communication aid to tell the adult how many objects there are).
