Speech and communication milestones vary widely, and worries about toddler replacing r and l with w and y, here is what you need to know.
The short answer
Gliding is a phonological process where R and L sounds are replaced with W or Y, such as "wabbit" for "rabbit" or "yeg" for "leg." This is one of the last phonological processes to resolve, often persisting until age 5 or even 6. Gliding is normal and expected in toddlers and preschoolers, and speech therapy is typically only recommended if it persists past age 5 to 6.

What Parents Should Know
According to ASHA, AAP, NIH guidelines, gliding is a phonological process where R and L sounds are replaced with W or Y, such as "wabbit" for "rabbit" or "yeg" for "leg." This is one of the last phonological processes to resolve, often persisting until age 5 or even 6. Gliding is normal and expected in toddlers and preschoolers, and speech therapy is typically only recommended if it persists past age 5 to 6. At 18-24 months, gliding is universal at this age. R and L are among the latest-developing sounds in English. No toddler is expected to produce these sounds correctly, and W and Y substitutions are the norm. It is generally considered normal when your toddler or preschooler says W for R and L in most words. However, you should contact your pediatrician promptly if your child was producing R and L correctly and has lost these sounds.
Normal vs. Concerning
By Age
What to expect by age
18-24 months
Gliding is universal at this age. R and L are among the latest-developing sounds in English. No toddler is expected to produce these sounds correctly, and W and Y substitutions are the norm.
24-36 months
Gliding remains completely normal. Most children under 3 use W for R and L consistently. Some children may begin to produce L in some positions while still gliding R.
3-4 years
L sounds may begin to emerge, especially at the beginning of words. R sounds are still commonly glided. Gliding is considered normal at this age and does not require intervention.
4-5 years
L sounds should be mostly mastered. R sounds may still be glided and this is within the normal range, though some children begin producing R correctly during this period. Intervention is typically not recommended until closer to age 5 or 6.
5-7 years
Both R and L should be produced correctly by age 6 to 7. If gliding persists past age 6, speech therapy is recommended. R sounds are among the most commonly treated speech sounds in therapy.
What to Tell Your Pediatrician
- Describe when you first noticed toddler replacing r and l with w and y and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if your child is over 5 years and still glides both R and L sounds.
- Mention if your child is becoming frustrated or self-conscious about their speech.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Your toddler or preschooler says W for R and L in most words
- Your child is under 5 and still glides R sounds to W
- Your child has begun producing L correctly but still glides R
- Your child can sometimes produce R or L in some word positions but not others
- Your child is over 5 years and still glides both R and L sounds
- Your child is becoming frustrated or self-conscious about their speech
- Your child is entering school and gliding affects their confidence
- Your child was producing R and L correctly and has lost these sounds
- Your child is over 6 years with persistent gliding and it is affecting academic performance or social interaction
What You Can Do at Home
- Keep track of when you notice toddler replacing r and l with w and y — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that your toddler or preschooler says W for R and L in most words — this is generally within the range of normal.
- At 18-24 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Talk, read, and sing to your baby frequently. Narrate daily activities to build language exposure.
- While monitoring at home, seek immediate care if your child was producing R and L correctly and has lost these sounds.
Related Conditions
Child Cannot Say the R Sound
The R sound is one of the most challenging English sounds and is typically not expected to be mastered until age 6 to 7. Substituting W for R is very common in toddlers and preschoolers and is not a concern before age 5. If R errors persist past age 6, speech therapy is recommended and is usually very effective.
Child Cannot Say the L Sound
The L sound is typically mastered between ages 4 and 6. Substituting W or Y for L is common and normal in toddlers and young preschoolers. If your child cannot produce L by age 5 to 6, speech therapy can help. L is generally easier to correct than R and responds well to therapy.
Toddler's Sound Pattern Errors Not Resolving
Phonological processes are normal sound pattern simplifications that young children use as they learn to talk. For example, saying "goggy" for "doggy" (fronting) or "poon" for "spoon" (cluster reduction). These patterns should gradually disappear by specific ages. If patterns persist beyond their expected resolution age, a speech-language evaluation is recommended.

Accent vs Speech Disorder in Bilingual Toddlers
When toddlers grow up hearing more than one language, they naturally blend sounds, patterns, and accents from both languages. This is normal and healthy, not a speech disorder. A bilingual child may pronounce some sounds differently than monolingual peers because they are learning the sound systems of two languages simultaneously. True speech disorders affect both languages equally, while accent influence appears only in specific sounds borrowed from one language to another.
Ear Fluid Affecting Baby's Speech Development
Chronic or recurrent middle ear fluid (otitis media with effusion) can temporarily reduce hearing by 15 to 40 decibels, which is like hearing through water. During critical periods of language learning, this muffled hearing can impact speech and language development. If your baby has frequent ear infections or persistent fluid, discuss the potential speech impact with your pediatrician.
Will Ear Tubes Help My Child's Speech?
Ear tubes (tympanostomy tubes) can restore normal hearing by draining persistent fluid from the middle ear. Many children show speech and language improvement within weeks to months after tube placement, particularly if hearing loss from fluid was contributing to their speech delay. However, ear tubes alone may not resolve all speech delays, and some children benefit from speech therapy alongside tube placement.
