Stopping
/v/ → /b/
Typically resolves on its own by around age 4; worth a check-in if it persists.
What helps →
Stretch /v/ as a long buzzy "vvvv" — /v/ is a fricative (held), /b/ is a stop (quick pop). Have the child feel the buzz on their lip.

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

Touch the throat — /v/ buzzes, /f/ is silent. Have the child feel the vocal cord vibration on each /v/.
Practical starting points for parents and SLPs. Always follow your SLP's plan if your child is in therapy.

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.

Most children produce /v/ correctly by age 5. About half can do it by age 4. /v/ is a mid-late developing fricative.
Both patterns (stopping to /b/, devoicing to /f/) are developmentally typical up to about age 4. If they persist past age 5, an SLP check-in is worthwhile.
/v/ requires sustained airflow AND voicing through a precise lip-and-teeth position. Some children get the position right but stop the airflow (/b/) or drop the voice (/f/).
Show the lip-and-teeth position in a mirror, feel the lip buzz with a finger, and use minimal pairs (vine/fine, vest/best) to train voicing and manner.
If /v/ is being replaced with /b/ or /f/ past age 5, see an SLP.
Yes — /v/ is highly treatable at any age. The lip-and-teeth position is visible and the voicing is easy to feel.
