Language

My autistic daughter called chips 'shishy fips', chocolate, 'locky' and her sister Laura, 'Lawley', for some time. I just think it is a developmental stage that most children go through before the brain, vocal chords, tongue and lips become fully co-ordinated. Some sounds, and sound combinations, are more difficult to make than others

It may just be language development and how children incorporate new words? My 8 year old nephew couldn't say "Despicable Me" when the film came out, he called it "speckly knees".

I can only speak from experience. My son for many years had difficulty with language particularly with some phrases. We were told by a speech and language person to use the correct phrase in a reply rather than correcting. This difficulty remained until he was in his teens, but eventually he got it right.

However I had an aunt who used to use similar but incorrect words and she was not autistic.

I have no idea, but saying words wrong isn't uncommon, even in older people. My grandad called a museum a mezooum and my partners gran called chipolatas chipolalees, and nosy parkers became snooky pokers.
