Gliding
/l/ → /w/
Typically resolves on its own by around age 6; worth a check-in if it persists.
What helps →
Open the mouth wide and watch in a mirror so the lips don't round to /w/; cue "tongue up to the bumpy spot."
Speech Sound Guide
The /l/ sound typically develops by age 5. This guide covers when /l/ develops, what typically goes wrong, simple ways to practice it, and over 85 /l/ words organized by position.

A child still substituting or distorting /l/ after age 5 is a good candidate for a speech-language evaluation — earlier if they're hard to understand or frustrated.

Slow the sound to a long "llll" so the tongue tip lands firmly on the alveolar ridge instead of bunching mid-mouth.
Practical starting points for parents and SLPs. Always follow your SLP's plan if your child is in therapy.
Every word from the Sound Safari practice library. The /l/ in each word is bolded.
Minimal pairs differ by a single sound — the heart of phonological therapy. Tap a card to hear it, or tap “vs” to hear a pair back-to-back.

"Given a verbal model, [student] will produce /l/ in the initial position of words with 80% accuracy across 3 consecutive sessions."
Sound Safari logs every trial against your goals and writes the SOAP note for you.
Most children produce /l/ correctly by age 5. About half can do it by age 3. Saying "w" for "l" ("wamp" for "lamp") is normal until around age 4–5.
Yes — replacing /l/ with /w/ is called gliding and is developmentally typical through about age 4–5. If it continues past age 5, it's worth a check-in with an SLP.
/l/ requires the tongue tip to land on a specific spot (the bumpy ridge behind the top teeth) and stay there, which takes more tongue control than most early sounds.
Help them feel the bumpy spot with their tongue tip, practice holding "llll" in a mirror, then chain it to "la, la, la" before whole words. Use the word lists above.
If /l/ is still being replaced with /w/ or /y/ after age 5, or earlier if your child is hard to understand.
Yes. /l/ is treatable at any age. Most older kids and adults make rapid progress once they feel the right tongue placement.
