However, the fact that the baby has mild atrophy suggests that she may need some extra help in developing the basic skills.
Correct the atrophy in the brain might slow her development. U need to assist her in this case.
I working in Pediatric hospital and one of my patient is a child 13 month old, she unable to stand and mainly there is no weight bearing, when I hold the child in upright position she flex her hips, knees and
ankles.
This might suggest that she could have set flexor tone. First U need to break that. Lifting and carrying positions also help s here.
child able to roll and sit and creep and also has good recognition.
she received 15 treatment session of weight bearing ex's and passive ROM
and place her on stand table.and no improvement
Creeping indicates that the child weight bears on shoulders and hips, now the question is has the dissociation taken place ? From ur post I doubt it.
