A baby’s trunk is an essential aspect of physical development, involving the muscles of the stomach and back.

As your infant grows, developing and strengthening trunk muscles will help them achieve important milestones such as:

  • sitting
  • crawling
  • walking

Proper trunk control enables your baby to maintain balance and move efficiently against gravity, making it a crucial step in their motor development.

There are several exercises and tools that you can utilize to help your little one enhance their trunk strength.

And we are going to cover them for you in this article.

One effective activity you already know from our other articles – tummy time.

As your infant becomes more capable of supporting their body weight, you can introduce sitting exercises.

One such activity is prop sitting – where your baby sits between your legs, and you provide gentle support to prevent falls.

Focusing on your baby’s trunk development is instrumental in ensuring a strong foundation for their movement and balance as they grow.

This article explores the core aspects of strengthening your baby’s trunk.

And will give answers to many of your concerns, among them:

  • What is a baby’s trunk?
  • What is trunk control?
  • How can I strengthen my baby’s trunk?

Let’s dig into the current topic.

Understanding Baby’s Trunk

Developmental Importance

Your baby’s trunk plays a crucial role in their overall motor development.

A strong trunk helps infants achieve important milestones such as sitting, crawling, and walking.

Trunk strengthening also supports proper posture and prevents potential future problems such as poor body mechanics and back pain.

Trunk Components

The trunk, also known as the core, is comprised of several muscle groups.

These muscles work together to provide stability and movement for your baby:

  • Abdominal Muscles: These muscles are located in the front part of the body and aid in stabilizing the spine and promoting balance.
  • Thoracic Muscles: Found in the mid-back region, these muscles contribute to trunk stability and support upper body movement.
  • Lumbar Muscles: Located in the lower back, these muscles play a vital role in maintaining posture and supporting the spine during daily activities.

To help your infant develop a strong trunk, there are various exercises and tools you can use.

Here are a few ways to support your baby’s trunk development:

1. Tummy Time

Place your baby on their stomach to help them engage their trunk muscles.

This activity can be started as early as the first days of life, gradually increasing the duration over time.

As mentioned above, you can learn more about tummy time practices from our dedicated articles.

Tummy time toys can be used to encourage your infant to stay engaged and enjoy this activity.

2. Ball Exercise

When your baby is developed enough to hold their head (not mandatory, but will make the activity more entertaining for them), an exercise ball can be used to promote trunk strength development.

Gently place your child on the exercise ball, and support them as they lean forward and backward or side to side.

This helps to engage and strengthen the baby’s trunk muscles.

3. Rolling Over

Help your little one build up the trunk muscles for rolling over with a gentle exercise.

Place your infant on their back or side-lying and slowly guide them into rolling over.

This movement encourages trunk rotation and engages crucial trunk muscles.

Developmental Stages And Trunk Control

From Lying To Sitting Position

During your baby’s early life, their trunk control starts as they develop head control and gradually move towards the sitting position.

As your baby gains strength in different trunk segments, such as the head, upper thoracic, mid-thoracic, and lower thoracic, this helps them adapt to the sitting position.

There are specific exercises that you can incorporate during tummy time to help strengthen your baby’s trunk:

  1. Motivate your baby to lift their head while lying on their stomach.
  2. Encourage reaching and grabbing, as these movements activate the trunk muscles.
  3. Gently roll your baby from one side to another, making sure to support their head and neck.

From Sitting To Crawling

The transition from sitting to crawling requires your baby to have strong trunk control, specifically in the lumbar and abdominal muscles.

As your baby practices these new motor skills, they work on coordinating their muscles together.

To help your baby progress toward crawling, try incorporating the following exercises:

  1. Provide support to your baby, allowing them to sit independently and maintain their balance.
  2. Encourage your baby to reach and grasp items from a sitting position, activating core muscles.
  3. Introduce supported transitions from sitting to crawling, like moving from sitting to hands and knees.

Crawling To Walking

As your baby’s trunk control develops, they will move towards the walking stage.

During this stage, balance becomes crucial, as your baby learns to stand and take their first steps.

To support your baby’s motor development throughout the process, consider using some of these exercises:

  1. Practice assisted standing, providing minimal support as your baby gains confidence.
  2. Help your baby walk by holding their hands, slowly releasing support as they become more stable.
  3. Introduce tummy time toys to encourage exploration and interaction while standing or cruising.

Employing these exercises and incorporating tools like tummy time toys, play mats & play gyms will help your baby develop essential trunk control.

Trunk control they need to achieve various developmental milestones.

Tummy Time And Trunk Strengthening

Benefits And Goals

Tummy time is an essential activity for your baby’s development as it helps strengthen their trunk, neck, and shoulder muscles.

Engaging in tummy time lays the foundation for developing gross motor skills like rolling, sitting, and crawling.

Besides improving coordination and balance, it also supports mental and physical development, enabling your baby to gain awareness of how to move in space.

Additionally, tummy time can help prevent head flattening (plagiocephaly) and torticollis.

Duration And Frequency

To incorporate tummy time into your baby’s routine, start slowly by placing them on their belly for 1 to 2 minutes, about 4 or 5 times a day.

Gradually, increase the duration of each session, aiming to reach 10 minutes 4 to 5 times a day.

It’s best to practice tummy time when your baby is awake and alert.

Remember to always supervise your baby during tummy time to ensure their safety.

Exercises For Strengthening Baby’s Trunk

Using An Exercise Ball

An exercise ball is a great tool for promoting physical therapy and strengthening your baby’s trunk.

Start by gently placing your baby on their tummy on the exercise ball.

Hold their hips and slowly rock the ball forward and backward.

This will encourage your baby to engage their core muscles and develop trunk stability.

Upper Back And Shoulder Exercises

To strengthen your baby’s upper back and shoulders, encourage them to engage in tummy time activities.

Place a fun object slightly out of their reach during tummy time to promote reaching and stretching.

Another activity is to lift your baby’s chest off the ground using a rolled-up towel or tummy time pillow under their chest.

By doing this, your baby’s arms and legs will dangle towards the ground, helping them get used to the motions of crawling while strengthening their upper back and shoulders.

Lower Body And Abdominal Exercises

To target your baby’s lower body and abdominal muscles during trunk strengthening exercises:

  1. Lay your baby on their back and move their feet up to their mouth and back down. This helps strengthen lower abdominals, like reverse baby crunches.
  2. Encourage your baby to push up onto their forearms or hands during tummy time. This engages their lower body muscles and strengthens their abdominals.
  3. Assist your baby in transitioning from a supine (lying on their back) position to a seated one. Place your hands under their armpits and help lift them to a seated position. This will improve their core strength and stability, which is essential for neurologic development.

Incorporating these exercises into your baby’s routine will:

  • help strengthen their trunk muscles
  • support their overall development
  • contribute to a strong foundation for their future physical activities

Tools And Toys To Support Trunk Development

Various tools and activities can strengthen your baby’s trunk.

Remember to monitor your baby’s progress and adjust tools and activities based on their corrected age and birth weight to provide optimal support for their trunk development.

Tummy Time Toys

To support your baby’s trunk development, introduce tummy time toys during their playtime.

Some toys and equipment that can facilitate trunk development include:

  • Mirrors: Stimulate visual tracking and promote head lifting
  • Soft, textured toys: Encourage grasping and reaching skills for improved trunk control
  • Moving toys (like the Tummy Time Crab): Encourage visual tracking and reaching

These toys encourage your baby to push up onto their forearms or hands, improving their reaching skills while simultaneously strengthening the muscles in their back.

Most popular tummy time toys are already curated by us in the tummy time section.

Sensory Stimulation Objects

Another way to support trunk development is through sensory stimulation objects.

These items, such as textured balls, rattles, or soft fabric toys, entice infants to explore various textures and sounds.

Play Mats & Play Gyms

Incorporating play mats and play gyms into your baby’s daily activities can further enhance trunk development.

These comfortable platforms encourage your baby to spend more time on their tummy or sitting, creating more opportunities to strengthen their trunk muscles.

Play gyms often include hanging or attached toys that inspire infants to reach, grab, or push up, further supporting trunk strength.

You can find reviews and guides in our Play Mats & Gyms section, the lighthouse article being about the 100% Non-Toxic baby play mats.

Handling Developmental Delays

Signs Of Delayed Trunk Control

You may notice developmental delays in your baby’s trunk control.

These can manifest through various signs, such as:

  • difficulty in maintaining a stable sitting position
  • struggling with rolling over
  • poor postural control during tummy time

Additionally, you might observe your baby having:

  • a floppy or loose trunk
  • stiff arms and legs
  • limited movement in specific positions

To accurately assess your child’s trunk control and identify any developmental delays, consider talking to your pediatrician and conducting a Segmental Assessment of Trunk Control (SATCo).

This assessment measures various aspects of trunk control, such as static sitting balance, dynamic sitting balance, and more.

Another tool is the Alberta Infant Motor Scale (AIMS), which evaluates the motor development of infants up to 18 months.

Working With A Pediatric Physical Therapist

If you suspect your baby is experiencing developmental delays in trunk control, reach out to a pediatric physical therapist immediately.

They will evaluate your child’s development by observing their lying position, postural control, and overall movements.

Upon identifying delays, the pediatric physical therapist may recommend specific exercises and interventions to help strengthen your baby’s trunk.

These exercises could include:

  1. Tummy Time: Ensure your baby spends enough time on their tummy to practice lifting their head and engaging core muscles.
  2. Supported Sitting: Guide your child to sit independently by supporting their hips and lower back, helping them develop trunk strength and balance.
  3. Rolling: Encourage your baby to practice rolling, starting from simple side-to-side movements and gradually progressing to complete rolls.

By closely monitoring your baby’s trunk control and working with a pediatric physical therapist, you can make a substantial difference in your child’s motor development.

Related Research

One longitudinal study examined the development of trunk control in healthy infants from 2.5 months to 8 months of age.

The study highlighted the relationship between trunk control and reaching.

By monitoring your child’s development, you can better understand their progress and determine the most effective exercises and tools for strengthening their trunk.
