• Children learn how to produce sounds based on how difficult sounds are to make with their articulators (e.g.: lips, tongue, teeth,etc..).  As they get older, children learn how to make more complex consonant sounds.  Because there is a wide range of when sounds develop, some children tend to develop sounds at a different rate than other children their age.  The following chart shows the expected age at which children should be able to produce these sounds.
