We should often want to have "Dialogue" with your children.

Some children fall in the middle of the spectrum, with a combination of single words and chunks. But none of this matters; these are just different paths to the same destination. Except in the rarest of cases, differences of this sort should not be cause for concern. The same goes for the rate at which children learn language. Some will produce their first word at the age of ten months or even earlier, and some will not do so until eighteen months or later.
