dd1 got put ona lot of waiting lists as a result of dx.
we already had Portage (I self-referred)
she had no SALT at all until we threatened to pull out of the Earlybird course (one of the reasons given for no SALT was that Earlybird was our support), and then miraculously got home sessions, one 2 hour session a fortnight. which were worse than useless, and the SALT tried to get dd1 to choose between 2 non-preferred activities, and ignored all her attempts at proper communication. the Earlybird course told us nothing we didn't already know (and a lot of stuff which was not actually true wrt statements, ABA, school places etc)
she got put on a waiting list for a totally inappropriate pre-school place; the place only came up once she was school age 
no OT (wasn't available at all for children with ASD, regardless of need).
a a result of this spectacular inaction, we did it all ourselves. ABA home programme. sourced an ASD pre-school placement, which was rubbish, but proved our point (that dd1 needed ABA)
pushed for and got (after 3 years
- yep, the 6 month timeframe really works!) a statement. dd1 is now at her second ABA school and her progress has been astounding.
but none of it has come from the nhs. at all.
