*As Jacy mentioned, a "speech delay" is so subjective, UNLESS it has been clinically deemed that your child has developmental issues/delays...such as Dysphagia or Apraxia. MANY boys, talk later anyway.
Einstein & Mozart did not talk until 3 years old. MANY "geniuses" were late in talking.
So, if a child really has a "speech delay" depends....the Speech Therapists, per the assessments, gauges how many words per the age, a child speaks (even partial words counts)....then from this, they see a quantitative degree to which a child is "delayed" in speech. THIS is what they did with my son, after an OVERALL developmental assessment, of the whole child.
My son, I have speech therapy for him because it is "free" AND as a Mom, I felt it would arm me with known techniques to educate myself on it. BUT, my son REALLY enjoys his speech therapy....and he LOVES his Speech Therapist... he knows, its something just for him, and it's special. AND, he enjoys learning from them. So, it's positive. And he is "proud" of his talking accomplishments. He has gotten less shy about talking... or even trying. AND it is also just a reflection of his 'natural' progression of talking... but the Speech Therapy does help and provides quantitative and qualitative "results." At least for my son. And his Speech Therapist is very good.
Don't be paranoid, don't be impatient. It will come.
My son sees a Speech Therapist, twice a month,...since he was about 19-20 months old. My son is now 2.5 years old. We use the tips they give us. It works... per each child. Each child is different.
The grandson of my daughter's teacher, also sees a speech therapist and he is 2.5 years old too. He has a different "progress" than my son who is the same age.
Our Speech Therapist says, that "boys" OFTEN talk later. It is gender based. She says that about 80% of her clients are "boys."
Don't rush it. DON'T compare your son to others. DO NOT be self-conscious about it. Just be proud FOR him. I used to get comments from other Mom's about "how come your son doesn't talk yet.... is something wrong with him?" No.. there is nothing wrong with my son. He had an overall assessment and he is even 'advanced' in several developmental areas. He is just delayed in talking. So what.
AND he is also bi-lingual, competently, in each language.
Each child will progress differently.
Remember, that "talking" does not have to be "perfectly" articulated either. Even singing is 'talking.'
Rest assured, it's fine. Don't alarm yourself unless his Speech Therapist is.
You do NOT need "products" to speed up his talking. Just use the techniques that the Speech Therapist uses, and duplicate that... because, CONSISTENCY and repetition is important. And as a Mom, you will learn from them, how to help your son best per HIS situation.
All the best,
Susan
