What to listen for
Listen for S creeping in as a substitution, and for the lip rounding that SH needs but S does not. A child producing SH with flat lips is usually drifting towards S even when the result sounds close.
Common SH errors
- Substituting /S/ for /SH/ (e.g., "soe" for "shoe")
- Not rounding the lips enough, causing the sound to come out as /S/
- Tongue positioned too far forward, resulting in a lisp-like distortion
- Substituting /CH/ for /SH/ (e.g., "choe" for "shoe")
- Producing a lateral (side-air-escape) version of /SH/
How to run SH practice
Short and frequent beats long and occasional. Five to ten minutes on most days produces more correct SH productions over a fortnight than one long weekend session, and it is far easier to sustain.
Work in one position at a time. Get SH reliable at the beginning of words before moving to the middle and at the end — mixing all three from the start usually slows everything down.
Keep correction light. Model the word correctly and move on rather than asking for a repeat every time; a child who feels tested talks less, and less talking is the opposite of what SH practice needs.
Tips for the SH sound
- Use the "quiet" cue: tell your child to put their finger to their lips and say "shhh" like they are telling a baby to be quiet.
- Emphasize lip rounding — have your child practice making a "fish face" or "kissing face" before producing the sound.
- Compare /S/ and /SH/ side by side: /S/ has a narrow smile with tongue tip forward, /SH/ has rounded lips with tongue pulled back.
- Use visual cues: show pictures of things that make /SH/ sounds (ocean waves, a quiet library) to reinforce the sound.
- Practice /SH/ in isolation until solid, then move to syllables (sha, she, sho) before tackling full words.
- Try the "creeping S" technique: start with /S/ and slowly round the lips and pull the tongue back until it becomes /SH/.
- Play sorting games where your child separates /S/ words from /SH/ words to build auditory discrimination.
