When to start sitting baby with support
4 Month Old Babies in Sitting Position, demonstrating Typical and Atypical Development
in supported sitting we see that Marty
is moving into the anterior-posterior
plains as he reaches for toys and then
sits back up he is able to pick up this
small toy and bring it to his mouth we
see good head control and chin tuck with
head in midline
babies of this age often reached with
one hand using the other upper extremity
for stability until full postural
control is developed his body is
supported only at the hips and pelvis we
see extension down to the mid thoracic
spine full extension down to the lumbar
spine will not be present until six
months even with minimal support at one
shoulder marty is able to turn his head
quickly and easily to localize and
grossly follow the toy in all directions
without losing his balance
in supported sitting owen exhibits a
momentary burst of head lifting in
midline but he is unable to maintain
that head position for even the briefest
period of time he is unable to turn his
head or look side to side even when the
examiner provides support at the upper
arm and shoulder
the examiner holds him high under the
armpits for maximum assistance Owen has
difficulty activating his vision in this
position unlike Marty who was able to
visually fixate on and begin to track a
toy the extremity movement that Owen
demonstrates is used to compensate for
his decreased strength control and
stability in the head and trunk
