I may have missed Christmas at bookstogether, but I'm just in time to wish you a happy Three Kings' Day with this carol or villancico, collected in Merry Navidad! Christmas Carols in Spanish and English by Alma Flor Ada and F. Isabel Campoy (illustrated by Vivi Escriva; Rayo, 2007):
The Three Wise Kings are coming
across the sandy deserts.
Among the gifts they're bringing
are the softest diapers.
I love that the three kings, in their wisdom, bring the baby diapers.
Feliz dia de los reyes!
