Delay In Walking

Most developmental screening is done by health visitors but, if they suspect a problem, they will bring it to the attention of the GP. Hence, even doctors who are not directly involved in developmental assessment must have knowledge of normal development. If a child has failed to reach a milestone at a given time but appears to be on the threshold of achieving it then a safe option is to review the child a month or so later to ascertain the progress made. If the child is nowhere near achievement of the milestone or there are other causes for concern then referral is required.

This is an approximate guide to some of the gross motor development of a child in the first three years of life but variation is common:

  • 6 weeks: sits with curved back, needs support. Head control developing.
  • 4 months: no head lag.
  • 6-7 months: sits with self-propping (hands pushing down on legs as he sits). Stands with support.
  • 9 months: gets into sitting position alone.
  • 10 months: pulls to standing and stands holding on.
  • 12 months: stands and walks with one hand held.
  • 15 months: walks independently (broad-based, high stepping), stoops to pick up objects. Creeps up stairs.
  • 18 months: climbs stairs holding rail. Runs. More mature gait when walking. Seats self in chair.
  • 21 months: walks backwards with imitation. Walks upstairs, two feet per step.
  • 2 years: goes up and down stairs alone.
  • 2½ years: jumps with both feet. Walks on tiptoe when asked.
  • 3 years: able to stand on one foot for a few seconds.

Most children are able to walk alone by 11 to 15 months but the rate of development is very variable. Some children will fall outside the expected range and yet still be fine in the end. Walking is considered to be delayed if it has not been achieved by 18 months.

Delay in walking may be simply variation of normal. Other common causes include:

  • Delay in motor maturation
    • Delayed motor maturation (often familial): this is the term to describe a late walker who is normal in other respects. The motor skills are of normal quality but are delayed. There may be an associated mild hypotonia. It is a diagnosis of exclusion.
    • Severe learning disabilities: there is a delay in all developmental areas but gross motor development is often less affected than fine motor skills, language and social skills. There may be some associated dysmorphic features and hypotonia is often present.
  • Abnormalities in muscle tone and power
  • Environmental factors: these can delay the onset of walking. In the extreme form, institutionalised babies kept in cots show delay in gross motor skills but this is rare. However, a similar process can be seen in children who have been ill and bed-bound for long periods of time. Emotional deprivation doesn't tend to affect these skills as much as others.
  • Other: rickets has been reported to delay walking; this is reversible if the disease is not too advanced.[4]

It is worth noting that obesity and congenital dislocation of the hip are not causes of delayed walking.[5] The issue surrounding baby walkers is not entirely clear but they are unlikely to cause significant harm. Two RCTs have suggested that they have no effect whereas two smaller cohort studies suggested that they delayed onset of walking by only 11-26 days.[6]

In assessing these children ask yourself:
  • Is this a true delay or a variation of normal?
  • Is the delay isolated or part of a broader developmental delay?
  • Are there abnormal neurological findings?
  • Are there any aetiological factors?


There are a number of essential questions to ask about any child suspected of developmental delay. Most of the answers should be in the health visitor's record.

  • Were there any problems in pregnancy? Antepartum haemorrhage or hypertension in pregnancy may be relevant.
  • Was the child a full-term normal delivery? Prematurity and problems suggesting possible intrapartum asphyxia should be noted. Only a minority of cerebral palsy is due to intrapartum asphyxia.[7] As babies of earlier gestation are surviving there is evidence that they are contributing more to the cases of cerebral palsy.[8]
  • Did the child feed well from the outset? A slow, floppy or irritable baby is of note.
  • Was there deep jaundice? A degree of jaundice is normal but severe jaundice can lead to kernicterus.
  • Past medical history
    • Has the child had any serious illnesses, such as meningitis?
    • Are there any other aspects of development that have been a cause for concern? This includes sitting, fine motor skills, speech and any other parameter.
  • Family history
    • When did the parents walk?
    • Are there any significant inherited conditions in the family? A family history of muscular dystrophy or some other neurological disorder may be significant.
  • Carer circumstances
    • Has the mother been trying to get the baby to walk? An overprotective or immature mother may be treating the baby like a doll - just feeding, changing and keeping in the pram or cot? Has the baby had a chance to try to develop motor skills? Has the mother encouraged these?
    • Consider untreated maternal postnatal depression.


  • Observation
    Put the child on the floor with some toys within easy reach whilst obtaining the history. Observe the following:
    • Does the child look normal? A syndrome like mosaic Down's syndrome may have been overlooked. Sometimes it is impossible to name a syndrome but the child looks strange.
    • Does the child look well cared for? Neglect and emotional deprivation cause developmental delay. Note the mother/child relationship.
    • Does the child seem alert and attentive? Is he interested in this new stranger or unconcerned about his surroundings?
    • What is the resting posture? Talipes or inversion of the foot can suggest imbalance of muscle tone and neurological abnormality.
  • Examination
    This is largely neurological and should be thorough. Look for strength, asymmetry of movement and the presence of primitive reflexes. Note particularly:
    • How is muscle tone? Passively flex and extend the limbs and pick up the child to assess muscle tone and control. Is there any asymmetry between sides? Does the head flop on being lifted? Does tone and muscle control feel normal for a baby of this age? Cerebral palsy is associated with spasticity eventually but at an early stage flaccidity is present.
    • Try to get the child to walk. Put the child down on his or her feet, at first keeping some control over the body. Does the child bear weight, or nearly do so, or does he or she flop down? Can the child stand with support but not unaided? Hold the child standing, facing towards the mother and encourage him or her to walk a few steps to her. Make encouraging and congratulatory noises. Is the mother spontaneously doing this too?
    • Test the plantar (Babinski) response. The plantar response is extensor at birth but, by the time the child is ready to walk, the neural pathways should have become myelinated and the response should be flexor.


A full developmental assessment is a very intricate and time-consuming task. A GP should be able to do a few basic tests and should learn the "feel" of a normal or abnormal baby, but full assessment is best left to those with the skills, the training and the time.

If the delay in walking is isolated with no other developmental delays noted, the only investigation required is a creatinine phosphokinase level. If cerebral palsy is suspected, the child may very occasionally need brain imaging to identify the extent of damage or to rule out very rare or potentially treatable causes such as tumours.[1]

This largely depends on the underlying causes - follow links.

General points

  • If the child reached all other milestones normally and seems on the verge of achieving this one: review in one month and, if the child can walk, that is fine. If not, refer.
  • Where there is general motor retardation in an otherwise normal child, reassure the parents.[1] The child will eventually walk without intervention although acquisition of other gross motor skills (eg running and cycling) may also be delayed. Occasionally, physiotherapy advice is helpful.
  • Delay due to environmental factors can usually be reversed provided children are given an opportunity to develop their skills. Look for signs of neglect where appropriate.
  • Poor parenting may be corrected but the basis of management is supportive.
  • A multidisciplinary approach may be required for more complex cases.
    • Children with severe learning disabilities need physiotherapy to address gross motor development problems and any hypotony.
    • In cerebral palsy, the prognosis depends on the degree of spasticity. Community physiotherapy or occupational therapy staff may help parents give more intense attention to the child to make the most of the limited potential. The sooner intervention can take place, the less will be any long-term deficit.[9]
    • Duchenne muscular dystrophy (DMD) patients also need physiotherapy as well as support for school. Genetic counselling is essential in these families.
  • Any other aspects of developmental delay need to be excluded or addressed.


  • If walking seems to be the only significant delay: referral to a community paediatrician may be in order for more detailed assessment but a paediatric physiotherapist or occupational therapist may be able to take a direct referral and offer appropriate management.
  • If this seems to be part of global developmental delay: refer to a community or general paediatrician. The cause of delay may be brain damage or unknown.
  • If this appears to be part of a previously undiagnosed syndrome: refer to a paediatrician for full diagnosis or exclusion. If a diagnosis like Downs's syndrome or cerebral palsy has already been made then an explanation should be given that delayed milestones are to be expected. It may still be appropriate to involve other healthcare professionals to make the most of the limited potential.
