Developmental Milestones 8-12 Months

Each child is different and will achieve milestones at different times in each stage. Some babies will walk at 10 months while others walk at 13 months. Developmental issues may first be recognized by health care providers within this stage. All balance and equilibrium reactions should be integrated during this period. The child will have a variety of postures and be able easily position self. The milestones of this age reflect the integration and ease of movement.

THE MILESTONES | 8 - 12 MONTHS

AREAS OF CONCERN COMPARISON OF PRE-TERM AND FULL-TERM MOTOR DEVELOPMENT

Full-termPre-term
9 months Standing: base of support
narrows rotates trunk, arms
by side
Standing: lordosis, wide base of
support, shoulder retraction
Crawls on all fours, trunk
Even
If crawling, wide base between
knees, lordosis, shoulder elevation
12 Months Stands alone, walks (at least
help); base of support narrow
Stands with support, base of support
narrow, arms out to side, stiffening
LE, lordosis
Transitions in and out of sitting
Using lateral weight shifting
Difficulty with transitions due to
poor lateral weight shifting

Atypical behaviors of 8 to 9 month-olds: Atypical behaviors of 10 to 11 month-olds: Atypical behaviors of 12 month-olds: Treatment interventions at this age should be directed toward improved mobility with weight-shifting on the lower extremities; sitting positions that include hip and knee flexion. The use of a small bench or corner chair may be used. Fine motor work to develop grasping patterns. Continued work on all gross motor skills and encouragement of lateral weight-shifting.
