Just had a reply to my email from 8th October, which asked neurologist whether my DD's initial chromosome tests were normal after all (she had said they were but genetics said not back yet), saying yes they were indeed normal.
She said she took so long to reply as she was on leave, strangely her secretary told me 4 weeks ago that she was back in the office on the next Wednesday 
Anyway we are just back at square one looking for rare conditions but have had a bonus extra few weeks of worry...yay!
