Of course Tally you are 100% correct there - what I meant was that after something like 5 to 10 seconds in a child's company, any judgements which might previously have been made based on their name would now be based on what they were saying or doing.
There is something to be had for connotations based on labelling though - people like Braham Norwich have done some very interesting research into the different and frequently wide-ranging views of professionals (ie teachers, Ed Psychs, SALTs, OTs etc etc) of labels such as autism ... there is certainly some substance in that particular issue!
