Oh heavens, a calendar thingie would be advanced by our standards.
Am getting referred for speech therapy for my 4yo.
He was assessed by a SALT, who says he has delayed speech rather than a speech disorder -- Salt gave these tips:
Make eye contact when speaking to each other.
(so that he sees how I form the sounds of words).
Get him to speak more slowly.
Speak more slowly to him and eunciate all the sounds in the words.
Comment on what he's doing when he plays, but don't ask questions (that can put him under pressure).
As much 1-to-1 as possible (he's eating right now, btw!).
She also said don't translate, make him work for what he asks for would apply in most cases, but NOT in ours, because we don't understand him lots of the time, anyway.
DS has non-systematic speech delay he does make most the sounds, but inconsistently from word to word, so it's harder to understand him than if he had a consistent system of sound replacement/funny words. As a result I am also trying
Get him to lengthen his words, even if he can't make all the sounds ("se'en", not "sen" for seven.
Make a game out of saying right every-day words he doesn't say right -- we are working on changing "fwi'al" into "cer-e-al". Just lenghting the sounds, and trying to get sssssss instead of fwee/fwi. Or "pleaZZZZuh", instead of "pluh" like he has been saying.
