Ninos or Ninas?
If I am referring to children, a mix of both boys and girls - would I refer to them as los ninos or las ninas?
you would refer to the group of mixed gender of children as Los niños. If there was to be a group of only boys it would still be Los niños. You only use Las niñas when you know that the group are all girls. If the group contained 29 girls and 1 boy you would still refer to the group as Los niños. Hope this has helped
