Here's what I have to say about this video, as a Speech/Language Pathologist who has worked with toddlers for over 25 years. Though this child is an exceptionally intelligent and language advanced child, he still demonstrates what's possible, even at age 3. The typical pediatrician will too often tell the concerned parent not to be concerned that their 2 1/2 year old is not talking. Give him/her time. Lots of kids don't speak until later. Wrong. Most are speaking, starting with single words around age 1 and full sentences by 3. Moral of the story, consult a Speech Therapist if you are concerned, regardless of what the doctor says.
