Infant 10 to 12 Months

Question 1

10mo sitting

Answer 1

rarely quiet in sitting, mostly moving/playing and both weight shifts
prefer tailor sitting (pre criss cross) and side sitting
some W sitting but less common

Question 2

sitting 11mo

Answer 2

all positions
uses more narrow BOS, lateral trunk flexion
*new: can hold a container with one hand while trying to place another container in it with the other hand (hand preference)
may revert to more primitive posturing when involved in a difficult fine motor task

Question 3

sitting 12mo

Answer 3

reaching for lower body (socks off)
superior pincer grasp
release improved for large objects

Question 4

creeping and climbing 10mo

Answer 4

still primary mode of locomotion

developing problem solving skills

Question 5

creeping and climbing 11mo

Answer 5

still primary mode of locomotion
very fast/efficient
can back down from furniture

Question 6

creeping and climbing 12mo

Answer 6

consistently uses trunk rotation
problem solving
efficient

Question 7

kneeling and half kneeling

Answer 7

10 - can easily transition to half kneel and play in this position
11 - can kneel without UE support
12 - hip and LE both control the posture; stable

Question 8

rising to stand 10mo

Answer 8

powered by LE

child moves to a single limb stance which demonstrates good concentric control of quads

Question 9

rising to stand 11mo

Answer 9

movement from squatting may be accomplished without UE support
try lowering from standing to half kneel

Question 10

rising to stand 12mo

Answer 10

same as 11 but with improved control

will play in squatting position

Question 11

salience

Answer 11

meaningfulness of a task to an individual

promotes active engagement and self initiation

Question 12

role of error

Answer 12

critical for enhancing motor performance

Question 13

standing 10mo

Answer 13

spends time standing on toes, which begins to prepare for push off phase of mature gate (elongates toe flexors)

Question 14

standing 11mo

Answer 14

*new activity: can stand without support

wide stance, high guard, ant pelvic tilt for stability

Question 15

standing 12mo

Answer 15

wide stance, independent, can lower body with/without support, more fixed UE

Question 16

cruising

Answer 16

all types of cruising, becoming more advanced, 1 hand support

Question 17

supported and unsupported walking

Answer 17

10 - forward walking with one hand held by caregiver
LE beginning to propel - called swing phase
11 - beginning to progress towards unsupported (wide stance of arms and legs, frankenstein) arms reaching out is influenced by goal of walking towards parent
*co activation of tibias anterior and gastroc
fall a LOT
12 - continue to refine, fast speed, short stride length and string phase, wide BOS, arms are up by side
(as stability improves, arms will no longer fix and will relax to sides or carry toys)
