What Parents Should Know
According to ASHA, AAP, NIH guidelines, secondary behaviors during stuttering, such as eye blinking, head jerking, facial grimacing, or foot stomping, develop when a child physically struggles to push through a stutter. These behaviors are a sign that stuttering is becoming more advanced and established. A fluency evaluation with a speech-language pathologist should be sought promptly, as early treatment can prevent these patterns from becoming habitual. At 24-36 months, secondary behaviors are uncommon at this early stage of stuttering but can develop even in very young children. If you notice your toddler physically struggling or showing unusual body movements when trying to speak, seek an evaluation. It is generally considered normal when your toddler repeats words without any physical tension or associated body movements. However, you should contact your pediatrician promptly if your toddler has multiple secondary behaviors and is becoming distressed about speaking.
Normal vs. Concerning
By Age
What to expect by age
24-36 months
Secondary behaviors are uncommon at this early stage of stuttering but can develop even in very young children. If you notice your toddler physically struggling or showing unusual body movements when trying to speak, seek an evaluation.
3-4 years
Secondary behaviors may emerge as stuttering becomes more established. Common signs include eye blinking, eyebrow raising, lip pressing, jaw tensing, and head movements. These develop as the child tries to force through blocks or repetitions.
4-5 years
If secondary behaviors are present, therapy should begin promptly. The longer these behaviors persist, the more habitual they become. Treatment addresses both the underlying stuttering and the secondary behaviors.
5-6 years
Children at this age may also develop avoidance behaviors, such as substituting easier words, avoiding certain speaking situations, or refusing to answer questions. These emotional and behavioral responses are additional signs that therapy is needed.
6-8 years
Stuttering with established secondary behaviors requires ongoing therapy. Treatment combines fluency strategies, desensitization to stuttering moments, and building communication confidence. Most children can significantly reduce both primary stuttering and secondary behaviors.

Toddler Stuttering or Stammering
Developmental stuttering - repeating sounds, syllables, or words - is very common in toddlers between ages 2 and 5, occurring in about 5-8% of children. In most cases it's a temporary phase that resolves on its own as the brain catches up with rapid language development. About 75-80% of children who stutter will stop naturally.
Toddler Gets Stuck and No Sound Comes Out
Speech blocks, where a child opens their mouth to speak but no sound comes out, are a form of stuttering that indicates significant effort and tension in producing speech. Blocks are considered more severe than simple repetitions and suggest your child would benefit from a fluency evaluation with a speech-language pathologist. Early intervention for blocking is important.
Toddler's Stuttering Is Getting Worse
If your toddler's stuttering has been increasing in frequency or severity over several months, it is important to seek a fluency evaluation from a speech-language pathologist. Worsening stuttering, especially with physical tension, secondary behaviors, or emotional distress, is a sign that therapy would be beneficial. Early intervention for stuttering is most effective before age 5.

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.
