At the end of 8 months, most babies can…
roll both ways (front to back, back to front)
sit on their own
support their whole weight on their legs
control their upper body and arms
hold and shake a hand toy
move an object from hand to hand
use their hands to explore an object
reach for a person they know
smile at themselves in a mirror
respond when others express emotion
copy speech sounds
track a moving object, and find one that is partially hidden
explore with hands and mouth
struggle to get objects that are out of reach
look from one object to another
watch a falling object
