DS has verbal dyspraxia, trouble processing and word finding. I knew something was wrong from about 2.5. And pushed for SaLT intevention. Sadly then the turnaround on appointments was about 18 months, and I didn't have mn telling me how to go about getting a timely intervention for him. He suffered for years in school.
Early intervention if you can get it is key to minimising any kind of delay or issue with children. Younger the better, so it is never best to wait and see.
And QT, being rude and posting with leaden sarcasm helps no one, least of all the OP you purport to support. Fanjo is talking sense, not posting the maudlin, aw hun you no ur babz best meme.
As for egos, I am sorry but your reaction does speak very much shouting down a differing voice for the sake of it, by being personal and attacking.
OP, get your DC down to the GP asap and get a referral for auditory testing, check for any organic reasons (ie glue ear) mouth formation etc, muscle tone. Worth also pushing for an OT assessment as well as a SaLT one.
And to be another doommonger, my poor little ds had a terrible time at primary, he was virtually unintelligable, had a bit of not very useful SaLT group intervention. He is now 14 and his speech is noticably different to his peers, stutters, stammers, hesitancy.
Happily he is also very funny and bright in all the top sets so I hope that his disability won't hold him back too much. Diagnosis at 9 however was way way too late for him/
