..... but when I say "Do this: Mummy" he says 'ayang".
I do know why- one of the joys of verbal dyspraxia (difficuties in producing something on demand) and perhaps some weird auditory processing thing but he says 'Mummy" perfectly- completely perfectly all the time and he doesn't even know he's doing it. People keep saying "wow isn't that great he said Mummy perfectly". Then I have to say 'er no he didn't- he doesn't actually know he's saying Mummy - it's just babble".
