Hi, DS1 is 4 years old, with ASD, severe speech delay/disorder and speech/sound difficulties.
I have noticed for a while that he says every word ending in 's' multiple times, as if he believes that as it ends in 's' it must be plural (my theory anyway). For example he says "Star war-war" for Star Wars, "mummy mummy mummy car" for Mummy's car, and similar to "Thomas and friend friend friend friend" for 'Thomas and friends' (Thomas the tank has lots of friends so his word equivalent of 'friend' can be repeated many times.
He even changes songs to accommodate this, rather than singing the actual words verbatim.
None of the 'professionals' I've spoken to appear to have heard of this before so I was just wondering if anyone out there had experienced anything similar?
