“My son can’t say the “r” sound.”
“We can’t understand what she is saying.”
As parents, we understand that babies don’t come out speaking clearly in full sentences, but what is appropriate? What is expected in early speech sound development? When to be concerned?
(See the GLP Blog’s Early Language Post for a straightforward summary and some key characteristics to look for in Language Development)
Summary of Speech Sound Development
The Baby Phase
Sounds that are the easiest to make- such as vowel sounds (ah, ee)- are typically made first. Babies first cries and purposeful sounds include lots of vowels.
Babbling also begins around 4-7 months. When babies babble, they make so many different sounds! They produce every sound in every language spoken in the world- including different tones, clicks, etc. As they learn their families’ language, they begin to drop the sounds they do not need.
The Toddler Years
Soon after, children begin to produce more consonant sounds purposefully. These new sounds tend to develop front to back. Meaning sounds produced with lips and tongue toward the front of the mouth, e.g., m, b, t, d, develop pretty early. This may be the reason that in languages around the globe the names children use for their parents, such as Mama, Papa, Maman, Mami, Dada, all use early developing sounds. There aren’t many languages where the word for “Mama” begins with an “r” sound for example.
Later sounds to develop include sounds that are produced further back in the mouth, such as “k” and “g.” These sounds are a little more challenging- perhaps because there is less visual information for a child to gather about the sounds. Try making a “k” sound and a “p” sound. The “p” is a lot easier to see how to produce the sounds.
Preschool & Beyond
Then more complicated sounds such as s, z, sh, f, & v (the “fricatives”) start to emerge. Fricatives are more challenging to produce for most children because your tongue, lips and teeth have to be held in a precise position while maintaining air flow. Try to make an “s” sound then switch to an “sh” sound- there is a lot going on! That adults can link sounds that are so different so easily takes really developed fine motor skills and it takes our littles a while to master such dexterity.

As children develop, they often use certain patterns to make words easier to say. For more information on Speech Patterns in Littles, see the GLP Blog Post here!
