Dear mums 
I have two autistic kids...
I have tried speech therapy and reading books...+ABA therapy etc and worked well with my daughter...she started talking since last year and is improving...
But the problem is my son.is not even babbling..
He makes sounds like:
Niaaa...Miaaa..kaaLa...grrrr
But never mumy or mama or any meaningful sounds :(
I am very worried...
His hearing is perfect...his receptive language is improving...
2 years ago he was never responding to any instruction with zero understanding...as if he would be a deaf...
Now...he responds to verbal.instructions although sometimes he gets confused...
Does speech need the cognitive abilities to mature before it comes out?
Recently i even suspected Apraxia in his lips as he cannot kiss...he can.only join his lips together and release without exerting qny.pressure...ge cannot :(
He cannot blow a candle and cannot pronounce letter F.. W...M...
Have you experienced similar symptomes with your ASD kids?
I am.confused if he cannot speak or refuse...but when.he cries...he never say mamy...or makes any purposeful sound...hd just cries EiiiiEiiiiEiii
This scares me further 
He will be 5 soon and I am very worried...

Sometime i worry if he would never talk

I started using.pecs with him.and he wonderfully discriminate the picture and gives me the right one for what he wants...so we are in.phase 3 PECS...
Sometimes i think it is just a matter of time and he will be improving... but then.when i think.again i get confused that he will turn 5 soon...and I must catch up and save him.before he reaches 7 years old...
I was told that if he foes not talk before 7...it will be impossible after 
But when i meet parents whose kids are older and non.verbal i get really frustrated and cannot even.sleep at night...i will end up depressed


Please advise me how PECS helped the speech to come out with your kids?
Also, what should I try?
I am.veeery WOoorieEEDDD
