Developmental Milestones

Helping Your Child Reach Key Developmental Milestones

As a parent, you eagerly await each new stage of your child’s growth—rolling over, sitting up, crawling, standing, walking, and running. But what happens when these milestones don’t happen on time? If your child is struggling with delayed motor skills, balance issues, or clumsiness, pediatric physical therapy can help them build strength, coordination, and confidence.

At Twin Hearts Physical Therapy, we specialize in helping babies, toddlers, and young children reach their motor milestones through fun, play-based therapy.

What Are Developmental Milestones?

Developmental milestones are key movement skills that children typically achieve by certain ages. These skills lay the foundation for mobility, strength, balance, and coordination. While every child develops at their own pace, significant delays may indicate a need for intervention.

Common Gross Motor Milestones

  • 2-4 months: Lifting head during tummy time

  • 4-6 months: Rolling over

  • 6-8 months: Sitting up independently

  • 8-12 months: Crawling

  • 10-18 months: Standing & walking

  • 18+ months: Running, stairs, & climbing

  • 2+ years: Jumping, balancing on one foot

If your child is missing these key milestones, early intervention with pediatric physical therapy can help them build the necessary strength and coordination to catch up.

Signs Your Child May Have Developmental Delays

Not all delays mean something serious, but some red flags indicate that extra support may be beneficial. If your child:

  • Does not roll over by 6 months

  • Has difficulty sitting without support by 9 months

  • Does not crawl or crawls asymmetrically by 12 months

  • Is not walking independently by 18 months

  • Frequently trips, falls, or struggles with coordination

  • Has difficulty with balance when running or jumping

These could be early signs of motor development challenges. Our pediatric physical therapists can help assess and support your child’s needs.

Signs Your Child May Benefit from Physical Therapy

Your child may need pediatric physical therapy if they are:

  • Not standing or pulling up by 12-14 months

  • Not attempting to walk by 16 months

  • Walking only on tiptoes or with stiff legs

  • Frequently falling or struggling with balance

  • Showing frustration with movement or avoiding walking

If you’ve noticed these signs, early intervention can make a big difference!

Common Causes of Delayed Walking

There are several reasons why a child might have difficulty walking:

1. Low Muscle Tone (Hypotonia)

  • Babies with low muscle tone may feel floppy when held and struggle to bear weight on their legs.

  • Strengthening exercises help improve stability and coordination.

2. Poor Balance & Coordination

  • Some children have difficulty with motor planning, making it hard to take stable steps.

  • Therapy helps with core stability, weight shifting, and postural control.

3. Torticollis or Plagiocephaly

  • Babies with tight neck muscles (torticollis) may struggle with proper head and body alignment, affecting mobility.

  • Early therapy improves posture, muscle balance, and movement patterns.

4. Prematurity or Developmental Delays

  • Preemies or children with developmental conditions (like cerebral palsy or spina bifida) may require targeted therapy to strengthen their lower body.

5. Toe Walking or Unsteady Gait

  • Some children walk on tiptoes due to tight calf muscles or sensory issues. While most kids will walk on tiptoes some, if this is the primary way they walk further evaluation may be needed.

  • Therapy addresses muscle flexibility and gait mechanics.
