Gross Motor Milestones in Infants 0-14 Months

Introduction[edit | edit source]

Specific gross motor milestones have general timeframes for skill acquisition, however, each child will set their own timetable. Skill acquisition is acquired through the interplay of the individual, the task and the environment.[1] Gross motor development will vary based on a host of factors including:

  • culture
  • child-rearing
  • household-income
  • parental involvement
  • infant handling
  • opportunities to practice
  • maternal education
  • number of family members
  • space for physical activity
  • sleep and play positions
  • equipment used[2][3]

Research shows there is a direct relationship between daily practices and motor development. Children that spend more time in active positions such as prone and standing have more positive motor development[4] outcomes than children who are in less active positions such as supine and sitting.[3] More specifically, decreased tummy time prone posture during awake time limits the infants' opportunity to practice postural control and antigravity movements.[2]

Acquisition of each motor skill facilitates new opportunities for learning and exploration. Learning entails the child adapting their behaviour to the current status of their body.[5] The following tables detail what one would gross motor wise during the first 14 months of life.

0-3 months[edit | edit source]

[6]
OVERALL 1-2 MONTHS 2-3 MONTHs
SUPINE physiologic flexion hip and knee;

unable to hold head in midline

sporadic head to midline;

sporadic cervical rotation;

increased extensor activity;

asymmetry of limbs

hands to midline;

symmetrical movement patterns;

PRONE increased physiologic flexion hip and knee;

elbows posterior to shoulders;

head to side

slight head lift to 45 degrees;

unable to hold head in midline;

flexion contractures decreased

able to push through hands;

start to lift head and shoulders;

head lift to 45 degrees

SITTING weight of head pulls them anterior;

shoulders anterior to hips;

unable to hold head in midline wide base of support (ring sitting)

need a lot of support at proximal trunk

pull to sit- head lag;

not able to hold head in midline

pull to sit-able to tuck chin and hold in midline;

vertical righting;

weight bear through hands (propped sitting)

STANDING supported standing;

reflexive moment in response to stimuli on plantar aspect

begin to accept weight;

astasia-abasia,
