NC I have heard stories on the SN boards that beggar belief
I do hope your friends get some help for their dc.
I can really relate to what you are saying wrt hcps....
Got my referral to see the rheumatoid arthritis clinic. It was cancelled (apparently I need the early RA clinic which is a specialist one)
Heard nothing for ages so rang them....my appt was the preceeding day but no one had informed me! (Got the letter telling me about the appt 2 days later)
Cue trying to get re-referred...hospital cant do it(?), choose and book cant do it (?) so has to come from GP again. Got another letter from hospital saying no appt yet, ring up in a few days. Rang yesterday. They have cancelled that referral now (?) so had to ring hospital and GP again.
No one knows whats going on and why I cant get into the Early RA clinic.
So, despite being supposed to ring me back yesterday, they didnt (yes, what a huge shock that was) so I rang them and I am now booked into the original clinic on my original appt date and time even though I have been told its the wrong clinic
Its sort of funny isnt it? Or would be if I wasnt in so much pain 
Dh has just come home and told ds1 that we are taking him to "Truckfest" in 2 weeks time. Sigh. The things I do for my kids
