What do the Spanish royal children call their parents and grandparents?
I briefly looked to see if this topic had been done before and didn't find any results. I hope I used the correct keywords...
Anyways, I've wondered for a while now, what do Elena, Cristina and Felipe call the King and Queen? I'm not too familiar with Spanish, but I know father is padre and mother is madre. However, they seem too formal of words to call ones parents.
Also, what do the Marichalar and Urdangarín children and the young infantas call their parents? What do they call their grandparents?
