Sorry if this is rambling...
DS2 (10) has Dyspraxia - of the bog standard motor sort. DS3 has Verbal Dyspraxia, and I can see that DS2 has none of his brother's issues re clarity of speech, disordered patterns etc. DS3's articulation of sounds is crystal clear.
However, it can take him an age to actually get his words out. He says he's thinking about the best words to use and whether the sentence he's about to say will make sense - we're talking 5 - 15 seconds or more sometimes before he can answer a "What did you do at school today?" sort of question. It can be infuriating if I'm in a rush, and while his friends are mostly patient it has caused some problems. And it's not all the time - there seems to be no consistency in it. Once he's started talking, there are no further pauses or delays.
His wonderful, on-the-ball teacher rang tonight - she's concerned because when practising the Reading bit of his Yr6 SATs with his scribe, he basically keeps running out of time because it takes him so long to start speaking/dictating to the scribe. He's very bright, and the teacher is worried that he won't do himself justice. She asked if we can practice this at home.
I suppose what I'm asking is - is this common? I can't find much about it online, mostly because I don't know what I'm searching for. It's not that his speech is slow, it's that he can't find his words. And will practice improve it? Is it part of the Dyspraxia, or something else?
