Hully, you just brought tears to my eyes. Slaps much needed and gratefully received 
You're right, I know, just feel rubbish at the moment. No theories for DD2, lovely GP said DD2 so well and healthy in all other areas she is just slower in this one. She has referred as she said it's a legitimate concern as DD2 should be reaching out by now.
I have googled far too much, that is never good for the soul
Gah
Fuck, arse, bollocks, wank.
There, that's better.
