I just finished this illustration for Houghton Mifflin/Harcourt to accompany a Spanish rhyme to be included in materials for their educational program.
The rhyme is said to have magical healing power. Parents gently rub or tap their fingers over a cut, bruise, or other injury in a circular motion, repeating the rhyme, and the injured child quickly feels better. "Sana" means heal.
Sana, Sana (Spanish)
Sana, sana,
carita de rana,
Si no sanas hoy,
sanarás mañana.
Heal, Heal (English)
Heal, Heal,
My little frog face.
If you don't heal today,
you'll heal tomorrow.
and me.
