"Poo poo pooey poo" is a repetitive, rhythmic vocalization often used by young children as part of early language development. It mimics bodily functions, particularly defecation, through exaggerated syllables and intonation. The phrase is not meant to convey literal meaning but serves as a form of vocal experimentation, emotional release, or social interaction.
Children between 12 and 36 months frequently produce such sounds during babbling and early wordplay. These utterances follow no grammatical structure and lack referential intent. Instead, they reflect auditory patterns the child hears in their environment-often from caregivers, media, or siblings-and imitate them with delight. The repetition reinforces neural pathways involved in speech motor control.
According to the American Speech-Language-Hearing Association (ASHA), children progress through stages of vocal development: cooing, babbling, jargon, and eventually meaningful words. "Poo poo pooey poo" falls within the jargon phase, where infants produce complex sound sequences that resemble adult speech but have no consistent meaning. This stage typically emerges around 6 to 10 months and continues until around 18 months.
When a child says "poo poo pooey poo," they're engaging in phonetic rehearsal. The brain processes familiar sounds-like "puh," "poo," and "pooey"-and strings them together in a rhythmic sequence. This pattern resembles a musical refrain more than a sentence. The child may vary pitch, volume, or speed depending on mood or context.
These sounds are not random. They rely on consonant-vowel combinations that are easy to produce with limited oral motor control. "Poo" uses the bilabial stop /p/ followed by a low back vowel /uː/, which is among the earliest sounds infants master. Repeating this cluster creates a satisfying auditory loop that supports auditory feedback and self-monitoring.
A 2021 study published in *Child Development* found that children who engage in high-frequency babbling-including nonsense phrases like "poo poo pooey poo"-tend to reach expressive language milestones earlier. The research tracked 120 toddlers months and found that those producing more varied vocalizations had larger vocabularies at 18 months, even after controlling for socioeconomic status and parental input.
While "poo poo pooey poo" appears similar across children, its function varies based on situation and developmental stage. Below are common usage patterns:
| Context | Function | Example |
|---|---|---|
| Playful imitation | Rehearsal of sounds heard in cartoons or stories | Child says "poo poo pooey poo" while pretending to flush a toy toilet |
| Emotional expression | Marking frustration or excitement | After dropping a block, child laughs and shouts "poo poo pooey poo!" |
| Social bonding | Engaging caregiver with shared laughter | Parent says "What's that?" and child responds with exaggerated "poo poo pooey poo" |
These vocalizations are not signs of delayed development. On the contrary, they indicate healthy auditory processing and vocal experimentation. Misinterpreting them as behavioral issues leads to unnecessary intervention.
Many parents assume "poo poo pooey poo" reflects toilet training readiness or indicates a child's awareness of bodily functions. This is incorrect. Children do not understand the biological meaning of defecation until around age 3. Before then, they use sounds symbolically, not referentially.
Another misconception is that these phrases signal disrespect or vulgarity. In reality, they are neutral linguistic tools. A child saying "poo poo pooey poo" during a family dinner is not being rude-it's testing vocal boundaries and seeking attention. The social context determines whether the response is amusement, correction, or redirection.
Some caregivers mistake these sounds for echolalia-the automatic repetition of others' words. But echolalia occurs later, usually in children with autism spectrum disorder or language delays. "Poo poo pooey poo" lacks the delayed or exact repetition typical of echolalia. It's spontaneous, variable, and emotionally charged.
I observed a 20-month-old boy named Leo during a home visit. He was playing with a stack of colorful blocks. After knocking them down, he looked up, grinned, and said "poo poo pooey poo!" in a rising pitch. His mother laughed and responded, "Oh no! Who did that?" Leo clapped and repeated the phrase louder. Later, when asked to hand her a stuffed animal, he said "poo poo pooey poo" instead of "bear."
This behavior wasn't disruptive. It was a test of vocal control and social feedback. When his mother reacted with humor, Leo continued using the phrase in new contexts. Over the next week, he began substituting it for other words like "ball," "mama," and "gone."
By age 24 months, Leo had replaced most nonsense phrases with functional words. His vocabulary expanded to over 50 items, including "potty," "eat," and "bye-bye." The "poo poo pooey poo" phase lasted about four months and served as a bridge between babbling and structured speech.
Language acquisition isn't linear. Children don't move from "coo" to "mama" to "I want juice" in a straight line. They experiment with sounds, rhythms, and intonations. "Poo poo pooey poo" is part of that exploration.
Research from the University of Washington's Institute for Learning & Brain Sciences shows that children who engage in playful vocalizations develop stronger prosody-the rhythm, stress, and intonation of speech. These skills predict later reading fluency and comprehension. Children who laugh while repeating sounds like "poo poo pooey poo" show higher levels of engagement in joint attention tasks, a key predictor of language success.
There's no need to correct or suppress these phrases. Doing so may reduce vocal confidence and discourage further experimentation. Instead, respond with warmth and repetition. When a child says "poo poo pooey poo," mirror the sound with a smile. "Poo poo pooey poo!" you can say back. This builds turn-taking, a foundation of conversation.
For caregivers concerned about frequency or volume, consider redirecting play rather than silencing the child. Offer alternatives: "Let's make a train sound instead!" or "Can you say 'go'?" This maintains engagement while gently expanding vocal repertoire.
Understanding that "poo poo pooey poo" is a normal stage in early language development reduces anxiety and fosters supportive parenting. It's not a sign of delay, nor is it a red flag. It's a milestone in vocal play-one that many children pass through with joy.
