I have posted before about my friends DS...he's 3 and having what appears to be a speech delay or possibly could be on the spectrum.
He's almost completely echolalic...but he is saying phrases that are pertinent to the situation...so if he's hungry and my friend offers him something to eat, he might respond with "But he was still hungry." from the very hungry caterpillar. He has a lot of phrases...tonnes...some are things he just mutters about undeer his breath and others, as I say are used t communicate.
He scripts from thomas a LOT too and also has begun glancing sideways at objects but not often...maybe a couple of times a day....I look after him and have only witnessed this literally about twice to three times a day...he'll bang a toy up and down for the noise and then put his eyes close to it and look out of the side of them.
He has begun recently to bring toys or objects to show his Mum and she sees this as a really good thing (as do I) but she's finally decided to speak to the HV about her DS echolalia and his obsession with tv and phones...he also wont use a fork but she spoon feeds him and is worried about his constipation too.
Do you think it is possible to have echolalia this much at 3 and come out of it? He's only just turned 3 and doesn't attend nursery yet.
