The correct answer is "proximodistal".

Infants exhibit a proximodistal pattern of growth meaning more proximal to the median or central muscles (i.e. trunk) will be the first one to exhibit movements then followed by more peripheral muscles (i.e. arms and thighs) then going distally to the forearms and legs and eventually to fine motor movements in the fingers and toes.
