When baby needs to eat - BABY NEEDS TO EAT! - And don't tell mama bison that baby has to wait. Mama bison will feed her baby wherever she wants, and neither you nor anybody else will do anything about it. That's the case in the two videos below, where baby let mama know that it was hungry and mama stopped. They don't want to disturb mama and baby, but they have someplace to be at the same time.
