RE: The average speaking rate is? a. 100 words per minute b. 120 words per minute c. 140 words per minute d. 160 words per minute.
DS1 - barely said any words at 21 months. By his 2nd birthday he was talking in full sentences so yes it can happen very quickly. DS2 - talking in full sentences at 18 months. I think they are expected to be able to string 2 words together by 2 so probably 3 to 4 words is about 2.5 on average I'm guessing.
