Why eyesight?  Couldn't they just carefully pick their way around by touch?
Or keep their distance from the nest?  Or as Stan said, they might have had
no parental care (I'm not sure if this makes a difference to the likely 
numbers and position of juveniles in herds).  Or if you like creative ideas, 
maybe the babies clung on or lived in pouches.  Or maybe they produced lots 
of offspring and just ate the ones they accidentally squished.
