Jаquin is а 12 mоnth оld bаby. He is able tо creep forward and back and move himself into a sitting position. He prefers to play in his exersaucer and baby walker and does not like to be on the ground. He is able to hitch forward in sitting and reaches all of his toys. He is not motivated to move by himself and cries for his mother to pick him up. She never lets his needs go unattended. Should a PT be concerned about his gross motor performance?
