What to listen for
Check that the sound is genuinely nasal and that the lips close fully. Where M is difficult, the reason is often nasal congestion rather than articulation, which is worth ruling out before treating it as a speech target.
Common M errors
- Substituting /N/ for /M/ (using tongue on ridge instead of lip closure)
- Not maintaining lip closure throughout the sound
- Weak nasal resonance due to congestion or structural issues
- Omitting /M/ at the end of words
- Substituting /B/ for /M/ (oral air release instead of nasal)
How to run M practice
Short and frequent beats long and occasional. Five to ten minutes on most days produces more correct M productions over a fortnight than one long weekend session, and it is far easier to sustain.
Work in one position at a time. Get M 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 M practice needs.
Tips for the M sound
- Use the "humming" cue: have your child hum their favorite song with lips closed to feel the /M/ vibration.
- Place a finger gently under the nose during /M/ — your child should feel air coming out of the nostrils.
- Practice the "yummy" sound: have your child rub their tummy and say "mmmm" like tasting something delicious.
- Start with simple words that begin with /M/: "mama," "me," "more," "milk," "moon."
- Sing songs with /M/ sounds: "Mary Had a Little Lamb," "Muffin Man," "Twinkle" ("my" and "me").
- Practice lip closure exercises: have your child hold a piece of paper between their lips for 10 seconds.
- Use mirror practice to confirm the lips are staying closed during the "mmm" portion of words.
