What to listen for
SH is the common substitution, producing "shair" for "chair": that is the stop portion going missing. T is the other, which is the release going missing. Naming which half is dropping out makes the correction much more targeted.
Common CH errors
- Substituting /SH/ for /CH/ (e.g., "shair" for "chair")
- Substituting /T/ for /CH/ (e.g., "tair" for "chair")
- Substituting /TS/ for /CH/ (e.g., "tsair" for "chair")
- Producing /CH/ without enough lip rounding
- Making the sound too prolonged instead of a quick burst
How to run CH practice
Short and frequent beats long and occasional. Five to ten minutes on most days produces more correct CH productions over a fortnight than one long weekend session, and it is far easier to sustain.
Work in one position at a time. Get CH 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 CH practice needs.
Tips for the CH sound
- Teach /CH/ as a "sneeze" sound — say "ah-CHOO!" to help your child feel the burst of air.
- Break it down: practice /T/ and /SH/ separately first, then combine them faster and faster until they merge into /CH/.
- Use the "train" cue: have your child pretend to be a train going "ch-ch-ch-ch" to practice the quick burst.
- Hold a tissue in front of the mouth — when /CH/ is produced correctly, the tissue should puff forward with each burst.
- Compare /SH/ and /CH/: hold /SH/ for 3 seconds ("shhhh"), then show that /CH/ is the same sound but as a quick pop.
- Practice /CH/ in fun words kids love: "chocolate," "cheese," "chicken," "cherry," "champion."
- Use hand signals: a slow sweeping motion for /SH/ and a quick chopping motion for /CH/ to reinforce the difference.
