Signs Your Child May Need Physical Therapy: Motor Milestones to Watch

Every child develops at their own pace, but some signs with movement, walking and balance are worth checking. Here is what to watch for, from infancy through the school years.

Every child grows and learns at their own pace. Still, many parents have a moment of worry: Should my baby be sitting by now? Why does my toddler walk on their toes? Why does my child trip so much more than other kids?

Trust that instinct. Getting a question answered early is always better than waiting. This guide covers gross motor milestones and common signs that a child may benefit from pediatric physical therapy.

What Pediatric Physical Therapy Focuses On

Pediatric physical therapy (PT) focuses on gross motor skills, the big movements of the body: rolling, sitting, crawling, walking, running, jumping, climbing, balance, strength and coordination.

If your concerns are more about hand skills, feeding, dressing, handwriting or how your child handles touch, sound and movement, those are usually areas for occupational therapy. See our guide to 10 signs your child may benefit from occupational therapy.

Motor Milestones to Watch

The CDC's "Learn the Signs. Act Early." program lists milestones most children reach by certain ages. Talk with your pediatrician if your child is not:

  • By 4 months: holding their head steady without support when you hold them
  • By 6 months: rolling from tummy to back, and pushing up on straight arms during tummy time
  • By 9 months: sitting without support
  • By 15 months: taking a few steps on their own
  • By 18 months: walking without holding on to anyone or anything
  • By 2 years: kicking a ball and running

Milestones are a guide, not a test. But if your child is behind, or seems to lose skills they had, check in.

Signs a Baby May Need PT

  • Always turns their head to one side, or has a tight neck (possible torticollis)
  • A flat spot on one side or the back of the head
  • Feels very stiff or very floppy when you pick them up
  • Uses one side of the body much more than the other
  • Strongly dislikes tummy time or cannot lift their head during it

Signs a Toddler or Child May Need PT

  • Walks on their toes most of the time after age 2
  • Trips and falls much more than other children their age
  • Has trouble with stairs, jumping, or keeping up on the playground
  • Gets tired quickly during physical play
  • Walks with feet turned in or out in a way that seems to cause problems
  • Has pain, or recently had an injury or surgery

Signs of Balance and Coordination Problems

  • Seems much clumsier than other children the same age, or often bumps into things
  • Has a hard time standing on one foot, hopping or skipping compared with peers
  • Struggles with ball skills such as kicking, throwing or catching
  • Has trouble learning to pedal a tricycle or ride a bike
  • Avoids climbing, playground equipment or sports that friends enjoy because they feel hard
  • Slumps or tires quickly when sitting or standing, or seems to have low muscle tone

What Happens at a Pediatric Evaluation

A pediatric evaluation is play-based. Your therapist will talk with you about your concerns and your child's history, then watch and play with your child to see how they move, walk, run, jump and balance. Standardized tests compare your child's skills with typical development for their age.

You leave with clear answers, a plan if therapy is recommended, and simple activities to do at home.

Early Intervention for Children Under 3

In New Jersey, children under age 3 with developmental concerns may qualify for the state's Early Intervention System (NJEIS), which provides evaluations at no cost to families. Your pediatrician can help with a referral, or you can contact NJEIS directly. Families can also choose a private evaluation with a pediatric therapist.

How Parents Can Help Every Day

  • Give babies plenty of supervised tummy time while awake
  • Limit time in car seats, swings, and bouncers outside of travel
  • Encourage play that uses both sides of the body, like crawling through tunnels or catching a ball
  • Make time every day for active play such as climbing, jumping, kicking a ball and riding a tricycle or bike
  • Celebrate effort, not just success

Frequently Asked Questions

When should I worry about my baby's motor development?

Talk with your pediatrician if your baby misses milestones such as holding their head steady by 4 months, sitting without support by 9 months, or walking by 18 months, or if they lose skills they had before.

Is toe walking normal in toddlers?

Toe walking is common when children first learn to walk. If it continues most of the time after age 2, or your child cannot stand flat-footed, have it checked by a pediatrician or physical therapist.

My child seems clumsy. Should I be concerned?

Some clumsiness is normal. If your child falls much more than peers, has trouble with stairs, jumping or ball skills, or avoids active play because it is hard, a physical therapy evaluation can check strength, balance and coordination.

Does my child need physical therapy or occupational therapy?

Physical therapy focuses on large movements like sitting, walking, running, balance and coordination. If your main concerns are hand skills, feeding, dressing, handwriting or sensory processing, occupational therapy is usually the better fit.

Do I need a referral for pediatric therapy?

In New Jersey, you can start physical therapy without a referral, but many insurance plans require a prescription from your child's doctor for coverage. Our staff will check your plan.

What ages does Holsman Children's Therapy Center treat?

We treat children from birth through age 21 at our Fair Lawn center.
