Gross Motor Delays: How to Support Your Child's Milestones

Watching a child grow, explore, and master new physical skills is one of the most rewarding parts of parenthood. From those initial, uncoordinated attempts at rolling over to the first steps across the living room, physical milestones mark your child’s growing independence and confidence.

However, it can be concerning if you notice your child isn't moving at the same pace as their peers, or if they seem to struggle with skills like sitting up, crawling, or balancing.

If you have questions about your child's physical development, it means you’re paying close attention. Gross motor delays are highly common, and identifying them early is the most effective way to help your child catch up. At On The Ball Pediatric in Orleans, we partner with families to transform clinical milestones into fun, everyday victories.

Understanding how gross motor skills develop can help you provide the targeted, playful support your child needs to navigate their world with confidence.

What Are Gross Motor Skills and Why Do They Matter?

Gross motor skills involve the coordination of large muscle groups responsible for whole-body movements. These foundational movements include rolling, sitting, crawling, walking, running, jumping, and lifting.

Gross motor development follows a predictable, bottom-up path. A child must first build core strength and neck control before they can stabilize their trunk to sit. Similarly, they need to master sitting balance before their nervous system can coordinate the complex, cross-body movements required for crawling and walking.  This also develops their sensory and nervous systems as they move, since sensing and moving evolves together. 

When a child experiences a gross motor delay, it simply means they are taking longer than expected to master these foundational physical patterns.

Subtle Warning Signs of Gross Motor Delays

Every child develops on their own unique timeline, and minor variations are entirely normal. However, there are distinct clinical markers that suggest a child’s neurological or muscular system requires a gentle, guided boost.

In Infancy (0–12 Months)

• Demonstrating a strong preference for keeping their head turned to only one side.
• Feeling unusually stiff or exceptionally floppy when you lift them.
• Struggling to push up through their arms or lift their head during tummy time by 4 months.
• Not sitting independently without support by 8 or 9 months.
• Showing no interest in crawling or scooting by 12 months.

In Toddlers and Preschoolers (1–4 Years)

• Not walking independently by 15 to 18 months.
• Walking primarily on the tips of their toes rather than using a heel-to-toe pattern.
• Frequently tripping, falling, or appearing exceptionally clumsy compared to peers.
• Struggling to climb stairs, kick a ball, or jump off the ground by age 3.
• Avoiding active physical play entirely, preferring sedentary activities due to rapid fatigue.

Common Root Causes Behind Developmental Delays

A gross motor delay is rarely caused by a single issue. When our pediatric physiotherapists evaluate a child, we look closely at several underlying physiological factors:

• Hypotonia (Low Muscle Tone): Children with naturally lower muscle tone have "looser" muscles, meaning their bodies have to work twice as hard to fight gravity and stabilize their joints.
• Hypermobility (Hyperflexible joints): when joints are hyperflexible, this takes away stability and the muscles have to work harder to hold the body together.  This affects some or all of the connective tissues that hold a body together (ligaments, tendons…). This also affects proprioception - which is the ability to sense what the joints and muscles are doing. 
• Diastasi Recti: This is when the linea alba, the connective tissue between the stomach muscles and its anchor, is stretched or has laxity.  You may notice a  bulge running down the middle of your baby’s tummy.  
• Brain or birth injury: This is usually picked up at birth, but sometimes it can get missed.  At On the Ball, we know how to pick up on those red flags and can refer directly to CHEO if we have any concerns. 
• Prematurity: A baby born early needs physiotherapy checkups to track development proactively and intervene early if concerns arise.  This is because being born early can affect how muscles, movement skills and sensory systems develop.
• Environmental or Positioning Factors: A lack of varied movement positions, such as insufficient tummy time or spending prolonged periods in restrictive baby gear, can limit early strength building.

How Pediatric Physiotherapy Empowers Your Child

Many parents worry that physical therapy will feel rigid or clinical for a young child. In reality, pediatric physiotherapy is entirely play-based. Children learn, map their brains, and build muscle through joyful exploration.

At On The Ball Pediatric, our specialized therapists design custom, game-based treatment plans that target your child's specific developmental gaps:

Therapeutic Play Systems

We hide therapeutic exercises inside engaging games. To build core stability and balance, we might have a toddler reach for bubbles while balancing on a soft foam pad, or crawl through an obstacle course of colorful cones to improve bilateral coordination.

Strength and Tone Modulation

If your child struggles with low muscle tone, we utilize targeted handling techniques and specific movement patterns to safely fire up “dormant” muscle groups, progressively building the structural stamina needed for standing and walking.

Parent-Implemented Home Strategies

The true magic of pediatric therapy happens between your clinical visits. We equip parents with simple, highly practical activities that fit seamlessly into daily routines.

A great example of this is dynamic diaper-change stretches. By turning a routine diaper change into a quick play session, you can gently guide your baby through fluid, active movements. Bicycle-pedaling their legs helps relieve digestive tension and releases tight hip flexors, while gently rolling their hips side-to-side dynamically stretches their lower back and wakes up their core muscles. These repetitive, playful habits build crucial body awareness throughout the day.

When to Seek Professional Guidance

When it comes to pediatric development, trusting your parental intuition is vital. Waiting to see if a child will simply "grow out of it" can cause them to develop compensatory movement patterns that are harder to correct later on. Early intervention utilizes the brain's natural neuroplasticity, making physical rehabilitation faster, easier, and highly successful.

If your child is missing key milestones, demonstrating asymmetrical movement, or if you simply have an underlying gut feeling that something is off, scheduling an evaluation provides clarity and peace of mind.
