Developmental Delays in Infants and Toddlers
Understanding Developmental Milestones
During the first few years of life, children typically develop motor skills such as rolling, sitting, crawling, standing, and walking in a predictable sequence. These milestones provide general guidance, not rigid rules.
A developmental delay occurs when a child takes longer than expected to achieve certain motor skills compared to peers of the same age.

It is important to understand that:
- Delays do not automatically indicate a medical condition
- Many children catch up with appropriate support
- Early movement experiences influence long-term physical confidence
Common Gross Motor Delays Parents Notice
Parents often seek guidance for concerns such as:
- Not sitting independently by ~9 months
- Not crawling or moving on the floor
- Avoiding weight-bearing through legs
- Not walking by 15–18 months
- Poor balance or frequent falls
Some children may skip crawling altogether, while others struggle with transitions like floor-to-stand.
Possible Factors That Contribute to Delayed Motor Development
Developmental delays can be influenced by many factors, including:
- Reduced tummy time in infancy
- Prematurity or low birth weight
- Muscle tone differences
- Limited movement opportunities
- Medical or neurological considerations

Physiotherapists do not diagnose medical conditions, but they assess how a child moves, plays, and interacts with their environment.
How Pediatric Physiotherapy Helps with Developmental Delays
Pediatric physiotherapy uses play-based, goal-oriented movement to support development.
A physiotherapy assessment may include:
- Observation of posture and movement patterns
- Evaluation of strength, balance, and coordination
- Parent discussion about daily routines and concerns
Treatment may involve:
- Guided play activities that promote motor skills
- Positioning strategies for home and daycare
- Parent education to encourage movement during daily routines
All interventions are individualized and family-centred, in accordance with the College of Physiotherapists of Ontario (CPO) standards.

Early movement experiences help children:
- Explore their environment confidently

You may consider an assessment if:
- You feel unsure or anxious about your child’s movement
- Your child avoids certain positions or activities
- Your pediatrician has recommended supportive therapy
Early guidance can help parents feel more confident and informed.
