How to produce /l/, common errors, and practice activities

Typical Development

Expected Mastery
5-6 years
The L sound is a common later-developing sound that children typically master between ages 5-6. It requires lifting the tongue tip to touch behind the upper front teeth while keeping the back of the tongue down—a movement that takes coordination. L errors often sound similar to W or Y substitutions and can persist into school age without intervention.
Tongue tip lifts up and touches the bumpy ridge (alveolar ridge) just behind the upper front teeth. The back of the tongue stays low.
Lips are relaxed and slightly open. They should NOT round (rounding creates W instead of L).
Teeth are slightly apart, allowing the tongue to lift freely.
Air flows around the sides of the tongue while the tip stays up. L is a voiced sound (vocal cords vibrate).
The most common L error. Lips round and the tongue doesn't lift, creating W instead of L.
The middle of the tongue rises instead of the tip, creating a Y-like sound.
In consonant clusters (like BL, FL), younger children may drop the L entirely.
L at the end of words sounds more like a vowel. The tongue tip doesn't lift enough.

Try these activities at home to help your child practice the L Sound.
Sing 'la la la' to a favorite tune. This repetitive practice helps build muscle memory for the L position.
Practice licking the roof of the mouth just behind the top teeth, like eating a peanut butter sandwich. This teaches correct tongue placement.
Practice L while smiling in a mirror. The smile prevents lip rounding which causes W substitution.
Say L words very slowly, exaggerating the tongue-up position. Then gradually speed up while maintaining correct placement.
Consider a speech-language evaluation if:
Most children master the L sound by age 5-6. Some development continues through age 6 for L in all positions, especially in consonant blends like 'play' and 'blue.' If your child is approaching age 6 and still consistently substituting W for L, consider a speech evaluation.
W and L differ mainly in tongue position. For W, the tongue stays down and lips round. For L, the tongue tip must lift while lips stay unrounded. Children who say W for L haven't yet learned to dissociate tongue tip movement from lip rounding.
Not necessarily. W for L in isolation is a common developmental error that responds well to therapy. However, if your child has multiple sound errors or other developmental concerns, a comprehensive evaluation can determine if there are broader speech-language needs.
You can support development by modeling correct L production, practicing L songs and games, and reading books with L words. However, if errors persist past age 5-6 or your child is frustrated, professional guidance ensures correct technique and faster progress.
