Analyzing Mouthful Behavior with Data: Why Do Babies Put Food in Their Mouths?

Have you ever noticed your child frequently putting toys or objects in their mouths ? This can be particularly concerning if your child continues to put objects in their mouths even after they've passed the oral stage . This behavior, called "mouthing behavior," can be a form of sensory exploration, stress relief, or interaction with the environment.

Today, I'm going to analyze moving behavior from the perspective of a Board Certified Behavior Analyst (BCBA), and talk about how to analyze behavior and conduct interventions when you discover behaviors that are concerning.

 

1. Mouthing Behavior, Why Does It Occur?

Mouth-feeding behavior is a natural way for children to explore the world through their mouths. It can occur especially when they have a high need for oral sensations, feel anxious or stressed, or are curious about their surroundings. It's important to understand this behavior not simply as a "problem to be fixed," but as an important signal that helps us understand a child's hidden needs .

 

2. ABA: Understanding Behavior with Data

ABA uses data to accurately understand a child's behavior and develop effective support strategies. Using a recent case of Mouthing Behavior I observed as an example, I'll introduce how ABA collects and analyzes data.

- Partial interval recording :

Partial interval recording is a quick and efficient way to record whether a behavior occurs within a specific timeframe . This method is useful for high-frequency behaviors, and because it only records whether a behavior occurs or not, it reduces time and effort during data collection. It is particularly suitable for observing behaviors that can occur briefly, such as mouthing.

To first determine how frequently my client's mouth behavior occurred, I observed several times throughout the day in 15-minute intervals, recording whether the mouthing behavior occurred at each interval. For example, if the mouthing behavior was observed in 5 of the 13 intervals in the morning session, it would account for 38.46% of all intervals.

Scatterplot : Using a scatterplot graph alongside the partial-interval recording method, you can determine whether the mouthing behavior occurs more frequently at certain times of the day. Visually representing the frequency of behavior occurrence by time period, as shown below, can help you identify behavioral patterns and better infer related factors.

The darker the color, the more times (5 or more) the behavior occurred. Mouthing behavior was confirmed to occur most frequently between 10:00 and 11:00 AM and between 3:45 and 4:30 PM.

- ABC Recording Method : Now that you've identified the frequency and time of behavior, what should you check next? Aren't you curious about why a behavior occurs so frequently at a certain time? Before recording the data , I often speculate that a certain activity or routine might be responsible for this behavior. This is where the ABC chart comes in. By recording the situation immediately before a behavior occurs (Antecedent), the behavior (Behavior), and the immediate consequence (Consequence), you analyze the causes and maintenance factors of the behavior.

Although I couldn't attach it to the blog because it included details about the child's life, it turned out that this client ended up engaging in more Mouthing Behavior during his unstructured "free time."

 

3. When is intervention necessary?

Mouthing behavior doesn't always require intervention. A child's behavior could be simply exploratory or a temporary phenomenon . However, in the following cases, active intervention with professional help is necessary.

Health and Safety : If your child's mouthing behavior puts them at risk for choking, ingestion of hazardous substances, or infection, immediate intervention is necessary. Your child's safety is our top priority.

Interference with development and learning : Intervention should be considered if the behavior interferes with a child's learning, play, or social interactions . For example, this may be the case if the behavior prevents a child from socializing with peers or concentrating on academic activities.

Function of the Behavior : If the moving behavior serves a function, such as satisfying a sensory need, relieving anxiety, or communicating , you need to find another way to fulfill these needs. With professional help, you can teach your child appropriate alternative behaviors and create an appropriate environment.

- Behavioral Patterns : If data analysis reveals that Mouthing Behavior is concentrated during certain times or activities, it may be helpful to adjust environmental or sensory factors related to it.

How do we develop an intervention strategy?

- Provide sensory replacement : Provide safe toys or tools that satisfy oral sensory needs. Teething toys with a variety of chew flavors, textured toys, and vibrating toothbrushes can be helpful.

- Environmental adjustments : By identifying the environment or situation, you can replace the triggering factors. For example, if your child tends to put a certain toy in their mouth, you can remove that toy or replace it with another. It's also important to create a comfortable environment that reduces stress and provide a sense of stability through predictable routines.

Reinforcement strategies : Provide positive reinforcement, such as praise or rewards, when your child exhibits appropriate behavior instead of the mouthing behavior. This helps your child learn the desired behavior and gradually reduce the mouthing behavior.

- Collect additional data : After implementing an intervention strategy, it would be beneficial to continuously collect and analyze data to evaluate its effectiveness and modify the strategy as needed.

 

Mouthing behavior is a behavioral pattern that can appear throughout a child's development. Today, we'll explore how to objectively understand a child's behavior and provide appropriate support using a data-driven approach!
