Thanks for your reply Britmum
We have suspected a language delay for awhile so the apraxia diagnosis wasn't a shock unfortunately. He will say "ellylwo" for "yellow" and "atha" for that so I think the diagnosis of apraxia is spot on. I wasn't expecting the dysarthria or sensory issues though. after the SLP pointed out that he wasn't using the muscles in his mouth/face properly, I can see how she diagnosed him. It's really the sensory issues I'm confused about. She is a very prominent SLP so I do trust her but of course she hasn't seen ichthyosis. The sensory issues are not her specialty so we've been referred to an OT. He does not respond when his hands and feet are touched and he has an extreme food aversion to fruit and will gag and vomit if he touches it :S. This is going to sound strange but she also said kids with sensory issues point their fingers really well instead of using their hands which he does but to be honest, I think he manages to use his hands well. Perhaps he doesn't have 100% mobility due to the thickness but it hasn't stopped him from doing what he wants! Having said that, he isn't able to use a spoon or fork well but I'm not sure if that is abnormal for a 24 month old??
His receptive language is extremely advanced and she said he is very intellegent which is why he is so incredibly frustrated that he can't communicate, poor thing. We are starting therapy once a week but have been advised that kids with apraxia need 3-5 sessions a week!!! And wouldn't you know, our insurance only covers $1,600 of speech therapy a week
just the once a week session will cost $6,000 a year! I'm just totally frustrated.
