We have a child in our family who is extraordinarily bright at 2yrs. old. He’s a pointer. You can ask him about anything ..names of people, reading story books.. colors and numbers, and he’ll point to every one correctly..but he will not say them. And even Latin letters and numbers!
He does say Mama and Dada and thank you..it’s as though he sees no reason to say these words since an adult is showing them to him in the first place so why repeat them.
I feel too much of an issue is made on how soon children speak....if there are no health issues causing this then let them be...they’ll talk when they are ready.
One of my newphews is the same. He is a chatterbox now.
