You are asked to evaluate an 11-month old baby who is delayed with gross and fine motor skills. The baby is able to prop sit when placed but cannot sit with an erect back to play with toys with her hands. You notice that she has an increased lordosis in supine and in prone. She is able to roll both prone to supine and supine to prone. When she prop-sits or when you hold her in your lap, you notice she keeps her neck hyperextended resting on her elevated shoulders. She has head lag on a  pull to sit. She can assume quadruped and rock back and forth with an increased lordosis, but then collapses to her stomach. She has no means of forward progression on the floor. Her muscle tone is low overall. She has a forward leaning trunk when supported in an upright standing position.  Her toes curl into flexion in this standing position.  She does not have protective extension to the front in sitting: USE THIS CASE TO ANSWER THE NEXT 2 questions.
