My DD has Sotos (and one of the 'symptons' - can't think of right word - is global developmental delay).
I have joined a Yahoo website (which is very informative although can be a bit over the top) but I have noticed that the Americans (no disrespect meant here) is that to get the help and support their child needs they have so say that their child is retarded neurologically.
I would NEVER say that my child is retarded, to me it is a derogatory term and I think 'global developmental delay' is a much nicer way of saying it.
Okay, by saying delay I am saying that my child will catch up, but actually I can say that she is catching up (albeit in her own terms).
I like to explain my DD condition as being on the bus behind everyone elses - her bus is running a little bit late. It will still arrive (get there) wherever 'there' may be, walking, talking, etc. and it will be in her own time.
If anyone I know mentioned 'retard' or 'retarded' (whether relating to my DD or not), I would be very offended.
The only time I have heard it is from USA. I was even watching ER last night (feel asleep on the settee and woke up about 1 am!) and ER was on (More 4). They were treating a boy aged 6 with Trisomy 18 (Edwards Syndrome) and they said it is very rare for a child of 6 to still be alive with Edwards Syndrome and that he was a 'retard'.
Made me go and give my DD an extra hug before I went to bed as no way do I think of her as 'retarded' and would be very offended if someone used this term.
Ignorance!
