How lips, tongue and jaw strength develop and when weakness affects speech clarity.

  • Chewing variety builds oral strength
  • Prolonged bottle or pacifier use can interfere
  • Blowing and straw play are useful exercises

What you can do at home this week

  1. 1Observe and note: write down what you see for five days, with times and situations.
  2. 2Reduce competing noise: less screen time, more face-to-face play in short, frequent bursts.
  3. 3Follow your child's lead, then add one step more than they can do alone.
  4. 4Repeat the same routine daily — progress comes from consistency, not intensity.

When to seek professional help

Book an assessment if the difficulty has lasted more than three months, if your child has lost a skill they previously had, or if daily life at home or school is affected. Waiting rarely helps; early answers change outcomes.
