Sorry I didn't explain what I meant by his speech being disordered, he just has a diagnosis of speech delay but he hasn't been assessed for 3 years so since 3 years ago obviously things have changed, it's more than a speech delay now, just some examples.
If he's poorly (he doesn't always communicate his poorly but when he does) he will come up to me and say what's up with your ears while pointing in my ears, but he means his own ears, he does that with everything. so say he banged his head he would come up to me and say ouch did you bang your head pointing at my head, I obviously know that he means his own head, but if he said that to anyone that didn't know him they wouldn't understand what he was doing.
Pronouns are reversed so 'you do it' means he wants to do it, can be very confusing.
He speaks as though he is the other person saying it, like he will say his own name then do you want your dinner, which means he wants his dinner.
He is communicating, but in a very odd way and it's been like this about 2 years now.
He can't answer questions or he can but very simple questions like it has to be very very prompted, for example if I know he has played with red paint at school (clue is in the fact he has red nails and red paint on his jumper) I will say what did you do at school today I'm met with a blank response so if I give him lots of prompting with little questions surrounding the answer he will eventually give me a one worded answer such as paint but I have to work very hard to get the answer.
He couldn't tell you his name or age or anything like that, he can answer things he's memorised the answer for but that's about it, you can ask him a question & if he knows the answer he'll say it but change the way you word the question then he wouldn't know even when the answer would be the same, he only knows in the way he learnt it iyswim.
To the passer by they would assume he was an ordinary 4 yr old boy cos he sounds so chatty and his speech is very clear, but spend 5 minutes with him and try speak to him and you know instantly it's all very abnormal.
My mums work friend asked how his autism affects him and her reply was - he can name you every single airline on the planet just by looking at the logo, but he can't tell you what his name is, sums it up perfectly.
There's lots of other examples I could give but you get the idea.
I do hope he learns to speak properly, and have a conversation, but I have every hope. I keep reminding myself he is still only 4 (5 in 2 months.) still very young really.
