OP - I really feel for you and can relate perfectly.
DS1 at 2 and a half had no speech at all.Didn't point.Didn't imitate,had bad coordination, nowhere near potty trained and behaviourally a wee sod.We aren't in the UK, so there were no HVs and everyone ignored my worries. I took him to everyone and anyone I could find for some guidance and got told 'less tv and talk to him more'.
Like I wasn't already talking my tits off.
As he turned 3.5, he bloomed.Toilet trained in a week, started pointing, loving books and developed a passion for maths and reading. He was diagnosed with HFA last year. They finally listened.
He is 6 now, has been at a mainstream nursery for 3 years and will go to a mainstream private primary in Sept. He is calm, very fluent in language, has a million opinions and is just a very easy child to parent.He has speech, occupational amd behavioural therapy and has no idea he is learning because he has so much fun! This is the happiest I have ever seen him in his life and I credit his nursery and therapists for that. He is honest to the point of rudeness and still obsessive at times but he is really getting there.
But 2-4 was a very sad, distressing time.I cried a lot.So YANBU to be upset.
I'm a single parent now and currently watching DS2, who has just turned 2, tip toe,flap and smack his way around the house.Guess what?No speech, no pointing either
No one is listening either yet, but I am resigned to it.We'll be ok, but I will be seeking support for him come Sept.
I am not remotely saying this will be the case with your son, but if there is help, take it!It has literally changed my son's life and we are all so much happier for it
